I bought an All American after your last blade sharpener video, I've not regretted it for a moment. That thing is lightning-fast, and super easy to use.

I did the same thing. I used my zero turn for 3 months before I used the All American. I was very impressed how well it sharpened the 3 blades and so quickly. Made a big difference in the cut quality and the grass blades for chopped up more on my mulching blades. Do not regret buying this....

[@ericb5447]

I also got the All American setup based on the last sharpener video you did. I went to harbor freight with the threaded pins that came with the sharpener and bought the cheapest grinder they sold that a pin threads into. I leave the flap sanding wheel on that grinder and it is dedicated to blades.

[@SparxI0]

I'm curious, why spend all that money? A new blade is $20 and there's a video on making a nice a jig for a bench grinder to accomplish the same. If I owned a landscaping company I would definitely invest in one. Or maybe if I owned an acreage and had to mow 4+ acres all the time. I just have a normal yard though

[@RyanMHawkins78]

We use an All American Sharpener for our lawn care company on anywhere from 6 to 21 blades per week depending on season and growth conditions. In my experience the 35* setting yields a QOC as good as the 30* while holding the edge longer and surviving impacts with small sticks, etc especially during leaf season. My blades last much longer compared to freehand with a vice and grinder/flappy disc I did before. They balance easier, and QOC is consistent from beginning to end of life on our blades. I also save a TON of time compared to before.

That all American would be great for the golf course. We sharpen blades constantly, and a consistent sharpening is key to after cut appearance. Which we usually can’t get with an angle grinder alone. Sometimes we even use a right angle die grinder with a roloc style disc and that doesn’t do any better with keeping the angle consistent.

@@ProjectFarm Please, for the love of God, test battery powered fans. It's in the mid 90's here in Georgia. We're all sweating more than we can drink. El Nino is coming, so it's only going to get hotter nationwide. We all just want to which brand has the best battery life, which puts out the most CFM per amp hour, which is the overall best value, how many decibles, etc. I trust you more than I trust the marketing teams at Ryobi, DeWalt, Makita, etc. This product test is relevant and will generate views. El Nino will bring heat and storms, both of which will knock out power. Without power, people don't have air conditioning and will resort to battery fans. We lost power for 9 hours here in Macon, GA on Sunday with the storms. We were all sweltering in the heat. Job sites are borderline unbearable in the sun. It's also relevant for camping, beach vacations, and every other place and time where having a fan would be nice. Heck, they're even nice to have when working on the car or mowing the lawn. This product test will help everyone. Use your science and engineering to point us in the right direction. We need you on this one!

I’ve been using a hand file for years and enjoy the time and patience it takes to get a consistent edge. Maintaining your blade so it doesn’t get too dull is also helpful.

[@mattwaters6987]

I totally agree! It's also rewarding too.

[@RealJeep]

I file three 20" blades with a file. It doesn't take that long and I can knock the burr off the back much easier than with a grinder.

[@kswis]

Agreed, it's a self reward and pride that you get by spending time, makes me smile every time I mow

[@itatane]

Plus, master putting on an edge with a file, and you can sharpen just about any edge, any where. Very little noise, good results and the only power requirement is calories.

[@solarmus923]

Frequent maintenance of the blade will absolutely make the process easier and much faster. (you'll get better results on your lawn too). I prefer the file and use a combo of a flat and a round file for mulching blades.

[@claycox6818]

I'm in the lawn care business. I've been using the All American sharpener for the past 3 years to sharpen the blades on my commercial mowers. I agree with everything you said about the All American. I believe it is one of the best investments you can make to keep good edges on your blades and do so in a short amount of time. As usual, thanks for the great comparison video! Also, I grease my sprockets every week when I sharpen my blades. I use the Red N Tacky after watching your grease review and am extremely pleased with it. I haven't had a sprocket bearing that I use this grease on fail in the last 3 years. I started using both products at basically the same time.

I use a hard disc on my All American Sharpener. It is super quick and more accurate than a flap disc. The resulting edge is absolutely beautiful like it was cut on a milling machine.

[@ProjectFarm]

Thanks for the feedback.

[@TrealTalk187]

What grit should you use for the hard disc?

[@victoryvisiontour]

@alanbarriga77 , I use a fine disc since hard discs remove material very quickly. The actual grit number is not critical. If a coarse disc is all you have, use very light force on it.

[@marcseclecticstuff9497]

Hey, I've got a mill... I'm an idiot, never gave it a thought. I'm watching this video trying to decide which one of these I should build, was leaning towards the All American design, but wanted to incorporate an adjustable rest for depth to keep it as flat and consistent as possible. Making a jig to hold the blades in the mill and whacking off the excess bits with carbide sounds a lot faster, easier, and more precise than any of these methods... Thanks!

[@jayr526]

My previous comment seems to have disappeared. I have used a four and a half inch angle grinder for years. I normally have a cut off disc on it, but recently I have been using a flap disc.. Apple the starting rope until the piston feels it is at TDC. I flip the mower on its side and remove the mulching blade with a 12 volt Milwaukee impact wrench. This takes less than a minute. Sharpening is done visually and is completed in a couple of minutes. The quality of the sharpening is sufficient for the quality of our lawn. Thank you for another wonderful video.

[@ProjectFarm]

You are welcome! Thanks for sharing!

[@libertarian1637]

Sharpened a lot of blades over the years and it’s hard to beat a simple nail into a vertical surface for a cheap and accurate blade balancer. Just put it on horizontally and if a side starts to fall it needs material removed. When balanced the blade will stay horizontal. I always liked hand grinding as it was fast and with practice you can get a good edge; though as I’ve gotten older a blade in a vise and an angle grinder does just as good and feels a bit safer. The bench grinder did make it easier though to keep a bucket of water near by to ensure the blade didn’t get too hot; hard to dip a blade when it’s in a vise.

[@sofjanmustopoh7232]

Nail on the wall is actually not very good as a blade balancer . It work in a pinch for rough balancing . The nail is a lot SMALLER than the lawn mower blade mounting hole . As the result the nail is NOT at the center of the blade . The blade offset location due to the nail . Would mean an small unbalance would Not be detected by the nail in the wall balancer

[@ProjectFarm]

Thanks for sharing.

[@robertheinkel6225]

It has been proven in several videos, a nail is not very accurate, but better than nothing.

[@libertarian1637]

@@sofjanmustopoh7232: May not be the “best” way but it works; been using this method for more than 6 decades and haven’t had any major vibrations or even minor ones. You can measure a lot of things good enough with a tape measure, sure you can measure things more accurately with a caliper or micrometer but at a point you get to demolishing returns of accuracy, especially when you’re dealing with something as coarse cutting as a mower blade. That said people can pay for whatever they choose and if you want to go that way go ahead. But a smooth nail at the center of a blade will work well enough and costs nothing as most people will have a nail sitting around.

Glad to hear that someone else uses an angle grinder with blade in the Vice. Are my blades 30 degrees? Probably not. Do they work fine? Yep.

I just use my 90degree angle grinder with a 60-80 grit screw on sanding disk. Works great, and is very easy. Another but slower method is my Worksharp knife sharpening system. A little slower, but helps with the multi angle mulching blades. Never had any balancing problems with either method.

[@tjinla9850]

I've had the All American for several years now. I like it a lot. It's bolted to a short piece of 2x4 wood block that I can easily clamp down with my Jawhorse vise stand under my car port. Using my battery powered Milwaukee grinder makes the system cordless and portable. I also use the Oregon magnetic balancer (also have the Mag 1000) which I believe is a real bearing saver on my mower decks. Love the whole set up. I hold a blade sharpening "party" a couple of times a year for my sons and a couple of neighbors. 🙂

Been mowing for years, many of them professionally.

Do not put any pressure, let the tool weight do the work and DO NOT overheat blade with any power tool method. Fast and effective. $285 for the all American...yikes, glad I learned to free hand with right angle grinder.

Good comparison as usual! Personally, I've been using an angle grinder with a flap disc on blades in a vise. Like sharpening a knife. Takes getting used to for proper angle but after a while they are perfect. Always check balance too as mentioned! It's much easier to fix an imbalanced blade then change a mandrel out! ;-)

[@ProjectFarm]

Thanks! Thanks for sharing.

[@robertheinkel6225]

I do the same, using 40 grit flap disk and free handling the angle grinder. Very fast and easy to use.

[@River_Miles]

There is no better method. Grass, sticks, stumps and rocks don't care if your blade edge is 20-45 Degrees. Resharpening will be needed regardless to get rid of chips. I like to shoot for30-40 degrees as any small rocks or branches hit will create smaller dings and make the blades last longer. You don't even need a vise. Vice grips and a piece of angle iron bolted to any suraface works perfect for sharpening even mulching blades. Flips the blade over to sharpen both edged and a single blade can be sharpened in 2 minutes with a flapper wheel.

[@whattheschmidt]

That's all I have done too and it has worked well. Sharp, balanced, close enough to the right angle....I doubt there's much difference between a 27 degree and 30 degree sharpening...That said I would buy the All American in this video if it cost around $100. No thanks at the actual price though. I do 40 grit if there's a big missing chunk and 120 grit to finish up flap disk.

[@kkarllwt]

I use a 60 grit , open cut 4 1/2 inch grinding wheel. I set the blade to be a little lower than elbow height. Do not grind out the nicks. It removes to much blade.

I think by the time you get the blades off and on the mower, the sharpening time isn't quite so important. None of the motorized equipment seemed to really take a long time. Personally, I tend to try to balance "cost vs benefit" when buying stuff. Based on that, I'm probably going to look closer at the Yellow Hornet, since I can likely stick a Pittsburgh/Chicago Electric (Harbor Freight) grinder in it and still get decent enough results. I don't use a bagger/mulcher, so I don't need to worry about the curved blades. By the way, did any of the sharpeners have an easy way to screw/bolt them to a workbench?

[@ProjectFarm]

Thank you for sharing!

[@francoiscaen3182]

I stopped using mine. Too many people ending in the hospital from ingesting metal bristles. The wood paddle is good enough and isn't going to kill me.

[@HumbertoYi0878]

The best brush by far is no brush. Use a wood paddle

[@ezloot4u433]

Look into the grill rescue. I love mine

[@ras8678]

@@francoiscaen3182 an alternative method I use for cleaning my metal grill grates is heavy duty aluminum foil. Doesn't take much, gets most of the gunk off and no harmful metal/bristles to worry about. If you have a lot of carbon/food buildup, I'll spray/soak them with vinegar prior then use the foil to remove/clean it. For porcelain coated grates, I use vinegar and baking soda soaking solution cleaning it with a soft scrub pad.

I have the RGB 712 and it works great. I like the fact it’s dedicated to only blade sharpening and I don’t need any other tools.

[@ProjectFarm]

Nice sharpener!

[@fredinit]

As always - great analysis. 80 Grit flap disk on a battery angle grinder with the blade held in the other hand resting on the edge of a garbage can when I want it good and sharp and balance it. Most of the time I just pull the spark plug wire, flip the mower on it's side, and grind it attached. Blade gets a new edge 2-3x season. Thing I like about the All American is it looks like it could be used to sharpen a lot of other things with a little modification to the jig. Yellow hornet needs adjustments and feat to bolt it down. As for files - should use whatever came out on top for your file test. Nothing says you can't use your own results.

This video like many others can double as a “how to” video. Some valid points, tips and tricks. The learning curve statement should be in everyone’s mind when they buy a new tool so as to temper one’s expectations. It takes a bit of time to get proficient at a skill, and making a quality cutting edge on any tool is without a doubt a skill. The way he used that file…100% skill. Really good job on this video, like every video. Awesome channel

When it comes to grind time I think its important to also consider setup time. Some of the grinders were "fast" but took a good few minutes to get set up so overall not as quick as the ready to go ones.

[@ProjectFarm]

Thanks for the feedback.

[@muffinbutton1484]

Whoa whoa whoa sir... there can be only one of us

[@timgebers2858]

I use a 60 grit flap disc freehand with the blade clamped in a vice as long as I don't force it it's worked great.

[@ProjectFarm]

Great feedback! Thanks!

[@kolt4d559]

Another fantastic video Todd! Personally what causes damage to the 2 blades I use is sticks and branches that are run over. That considered a nice file is the go to option. However if someone needs to maintain a few dozen blades on a golf course, sod farm, or local public works the more expensive sharpeners can be worth the investment. As a second comment I have a few video suggestions. Comparisons for the following categories: pruning shears, shrub shears, lopping shears, and maybe some handheld saws. All are items that can be utilized in maintaining ornamental plants, shrubs, and trees.

[@ProjectFarm]

Thanks! Thanks for the suggestions.

I’m more than happy using my $9 blade sharpener. I think $1200 for blade sharpening my $200 lawnmower is just a lil too much 😂 I’ll check out the Arnold sharpener tho .

[@volvo09]

I would consider the 1200 one a professional level tool, like if you ran a shop... It gives a perfect "flat" result which i'd expect if I paid to have a blade sharpened, vs doing it myself with a grinder.

Your videos are consistently the best way to compare and choose whatever device or tool is being tested. The tests are fair and let you know what problems are faced when using each item under test. This information is very helpful as are the comparative graphs you use to show performance parameters. If the viewer can’t figure out after watching, that is a problem you can’t solve. Please continue your quest for real performance. Anyone who wants real legitimate tests can count on you to deliver honesty and integrity in testing with your videos. I defy anyone to question your motives or purpose. You are by far the fairest tester I have come across.

[@ProjectFarm]

Thanks!

[@TheMaroney]

Great video. I think I would use a vise and my grinder with flap disks. As long as you can get the angle right it should be fine.

Whether I need or use a product in your vids doesn't matter. I watch them to learn. You have real-world testing that seems to be missing otherwise and it is wonderful to see your testing. The All-American is my favorite.

[@ProjectFarm]

Thanks!

[@deyyoung42]

I use a mill file on my mulching blades (mounted in a vice); 3-4 passes and done. I sharpen them weekly. Takes longer remove and reinstall the blades than it does to sharpen them. Your blades were way more dull than they should ever get, which is why it took so long - your grass will look better, too. No special setup, no dedicated space, and no expensive jig needed.

[@ProjectFarm]

Thanks for sharing.

[@tommytriglav5181]

The best sharpener is one that you use. I balanced and sharpened mine on a grinder last year. I ordered the 3 dollar stone you put on the drill and it worked quite well with the blade on the mower. I could see what part of the angle I was grinding and I adjusted the angle to match the blade angle. It took a few minutes and I was very happy with it. Nice and sharp in comparison to how it was

[@ProjectFarm]

Thanks for sharing.

[@CaptainBoobles]

Do you end up keeping many of the products you test, or do you sell them on (atleast the ones that haven't been destroyed during testing)? If so, what's the most expensive one you've kept hold of? Do companies ever follow up with you to improve their products or ask you to test prototypes? Would love to see a FAQ video!

[@tbelding]

In a past video (or two), he's mentioned that he donates a lot of them on. At least, those that survive.

[@Birb_of_Judge]

I'm going to be honest, I'd either use a fine file or a belt grinder Btw I'd love too see a review for different brands of 2x48/72 grinding belts

[@goosenotmaverick1156]

The way I beat em up, I hit em with an angle grinder without removing them. I sharpen at least monthly and usually replace yearly lol The belt grinder is an approach I never considered, I'll have to try removing and using that for sure for the blades on my brushhog. May be able to fit it up there without removing too haha

[@ProjectFarm]

I'm a flat file guy, but I got to admit that the guys building custom $300+ knives usually sharpen them on a belt sander. My Father uses a 2" belt sander for his riding mowers blades and it works well.

[@ProjectFarm]

Thanks and you are welcome!

[@stuartjohns2779]

One test you didn't do is to see how long the edge lasts. Abrasive wheels soften the blades so the blunten quickly. For almost every blade a file is the slowest method of sharpening but holds its edge way longer. This also applies to cold chisels and centre punches

[@ProjectFarm]

Thanks for the constructive feedback.

[@bdybybb]

Working in a hardware store while in high school, I sharpened hundreds of blades with a bench grinder and it was by far the best and easiest method. Even more important is a high quality blade balancer, not just the chinsy one you showed in the video.

[@BCS_guy]

Same! I worked at a lawn mower repair shop and I learned a lot about sharpening blades. If I had to buy one item (sharpener or balancer) I would buy a good balancer. I can get the blades sharp with an angle grinder (hopefully the angle would be close). But I would be confident that the balance would be spot-on.

[@ProjectFarm]

Seriously Dude, anytime I need to research a tool or process you have a video. Truly amazing channel! The "All American" seemed the best to me but also just made a good grinding technique dumb proof by holding the grinder for you at the correct angle. Since I grew up with having to do it with a file, I think I'll try the grinder free hand first. The tip about the correct wheel to get is also a huge help. Thanks again!

[@Shorty_Lickens]

I discovered 80 grit sandpaper and a power sander take about 28 seconds total to clean up the edge of a mildly dull blade. Anything more and I'd probably want some kind of a jig to guarantee the best angle. And a grinder or grinding wheel for a drill. (I just took my blade off the mower cuz it hasnt even been looked at in almost 5 years. Edge was OK, dull but not damaged.)

[@ASMR-soothingsounds]

I own the All American model 5002 for straight blades and can attest to the ease of use and the consistent sharpening of all my mower blades. This tool takes the guess work out of getting the correct angle and sharpens your mower blades in a very quick manner allowing you to get on to more important things. Highly recommended plus it's made in the USA!!

[@astaschak]

Interesting video, I only maintain 3 mowers and 2 lawns non commercially. So I typically only sharpen the blades once per season unlike a company would do weekly. They cut as many lawns a week as I mow my yard in a whole season so sharpening is kinda just my spring maintenance. Unless I bugger up a blade hitting something or it starts performing poorly during the season I won't bother. I either free hand an angle grinder with a hard disk, bench grinder, 1x30 belt sander, or a file. Kinda just depends on what tool is easiest to get to with the mess always in my home shop. I have used my little vertical manual mill and a custom jig too on a blade that was very badly damaged and should have been replaced but I didn't feel like running to the store.

[@ProjectFarm]

Thanks! Thanks for sharing.

[@EliminatorPerformance]

Great video PF! I have an idea for a video, Best File Handle? The ones I have are pretty cheap, I'm sure it would make for a good video and great test to see which ones hold up the best and offer the best ergonomics!

[@ProjectFarm]

Thanks! Thanks for the suggestion.

[@Steve_K2]

My mower is a battery powered Ryobi. Part of the post-mowing process for me is to tilt the mower onto its side and to sharpen the (mulching) blade in place with a file. The blade is never removed for balancing, and after three summers of doing this there's no perceptible vibration. Removing a blade is now in my rear view mirror, to be done only when replacing the blade. As little metal as a file removes, replacing appears to be "never."

[@ProjectFarm]

Thanks for sharing.

[@Michael-RI]

Good test. I used my new 4" belt sander from Harbor Freight to sharpen my blades and it worked very well and did not take long at all. A bit difficult to use on mulching blades but is doable. I did sharpen two standard blades which was easier and did a good job.

I'd be curious to compare the best to taking a Bridgeport End Mill and mill the edge at 30 degrees. Of course, the blade would have to be mounted in a vise perfectly in order to make sure it wouldn't move, but i bet it would make a perfect edge and cut the relief perfectly.

[@christopherbiomass7155]

I tried the Arnold style years ago on a blade that had seen more than a few rocks. It was next to useless. So I just free handed it with an angle grinder, similar orientation to the All American. More than good enough to cut grass.

When I was a kid we used to get a new lawnmower blade every spring, and this meant a trip to Canadian Tire. One time us 3 kids were sitting in the back seat squabbling over who was going to hold the new blade in its cardboard wrap on the way home. My mother sitting in the front seat immediately took the blade away and gave my Dad an earful about us kids cutting off our hands and stuff, all the way home. I bet he wished he had gone by himself :-)

[@Hiker_Guy]

I use a 4.5" angle grinder and a flap wheel with the blade clamped flat on my welding table. I sharpen once a year at the end of the season. I do the rear/flat surface first and then sharpen the angle until it meets. This is all you need to do; you do not need any specialized tooling or equipment. While 30* might be optimum, the grass doesn't know if the blade is 25* or 35*, but it does like a sharp edge. I have a cheapo balancer from Ace Hardware.

[@ProjectFarm]

[@MrLeavemikealone]

Angle grinder free hand in a bench vise and an impact wrench for removal. If I use the beam hoist to raise the tractor; I'm done in 5-10 minutes. I do use special jigs for hand knives but not the mower or even the chainsaws. I'm guessing most don't mess with a precision grind unless they are obsessively thinking it makes a big difference. Another thing I've noticed on brand new blades out of the box...They aren't sharp. They have the angle and perfect balance but what I consider a "blunt" edge.
