Pretty amazing new stropping/sharpening find.

Check this stuff out, it's incredible.

[@kevinAuman1]

Brother, I have learned and applied so much edge knowledge to my knife sharpening/honing/stropping technique from your vids and taken my blades to an entirely new level.... Thank you from an Iraq vet with no arm-leg hair left to test on lmao

[@DeanO]

I love it when new sharpening ideas are presented John, very cool!

[@jamescooper2618]

Really impressed how he is push cutting through the receipt paper! People say "big deal, its only paper" but push cutting through something with no stiffness is very difficult.

[@ActionHero29]

James Cooper indeed, and receipt paper is pretty thin..

[@peetsnort]

James Cooper i agree see my video on super sharp 10 dollars knife standing paper cut

[@robertbefford4190]

Im going to try it thank you

[@theone614]

In my experience reciept paper is ez to cut.

[@PoundSighEL]

Just ordered some on amazon. Can't wait to try it out

[@Mingebagz1]

You answered my question about these pads and I didn't even know you were going to in this video, you got my subscribe!

[@BudgetBugout]

Hm.... I think I have this sandpaper somewhere....

[@adriandelvecchio3917]

I started doing this a while back back but to make it even better you can move to move down in your pads 3m make a ultrafine and microfine you will love it almost mirror edge 🤙🤙

[@ColossalSwordFormAndTechnique]

This vs leather. Which is faster?

[@jdavis882]

Over leather and traditional strop compound? This hands down. However diamond compound for leather strops comes very close in speed and aggression.

[@peetsnort]

When I was younger and poor I could not afford the tools I needed and thought I could use brute force... Big mistake even the hardest steel flex and put you off angle

[@sageslarres]

What you are doing is called sharpening. Try getting a 6000 grit whet or glasstone. The kinds made for sharpening knifes. stropping is just finishing and is usually done with e much higher grit than 3000

[@johndough2785]

+Joakim järvinen Stropping is back strokes only.

[@sageslarres]

yes and do you know why? becouse stropping unlike both honing and sharpening is a method in which you straighten and polish the edge WITHOUT removing almost any material. This is why you use a piece of leather and a polishing compaund. as soon as you are using sandpaper of the grit he is using you are not stropping you are sharpening or possibly honing i guess however the grit is still to rough for that. You are removing material to forrm a new edge ( and yes you can sharpen something using only backstrokes)

[@TheBuddyboy1997]

+Joakim järvinen he's using the stropping form

[@billnewman1260]

This works! I watched the video, immediately went to Advance Auto and bought the 3M Trizact sandpaper. I only thought my RAT II had a razor sharp edge before. This method has taken "sharp" to the next level. Plus, the bevel is nearly mirror. A little stropping with green compound on leather, and I can see myself in the edge.

[@68MIKEILIKE1]

I cannot believe it. I bought this stuff in a pack consisting of 3000, 5000, and 7000 grit. I ran my kinives over it at 20 strokes per side on each grit and then ran them a couple of times over a piece of glass. My knives are now sharper than they would be with any sharpening system that I have used. They are like razor blades. Thankyou for the idea.

[@Xandrosi]

+michael meredith Curious if you are wetting the paper before use as 3M suggests? Very interested in the pack you discussed. Where can I find this please? 7000 grit would be fantastic for fine wood chisels!

[@68MIKEILIKE1]

I bought it on Amazon UK.

[@lovejesusu3]

I can't find 7000 grid on their website

[@LouBalestriere]

+michael meredith How did you run your knives, toward blade or spine? Also, it's tough to find 7k do you think stopping at 5K will give same results as shown in video? Does this replace the need to bring your knives to stones? Even if you kill the edge? Finally, do you think it'll work for my straight edge razors? I can't see myself not going back to my stones to set bevel/hone.

[@68MIKEILIKE1]

5000 will definately give you comparable results, ie, a razor edge. I ran the blades toward the spine. Hope this helps.

[@specopsbrat5130]

I am a mobile detailer in Tampa. I've used that product for the final stage of paint leveling, or removing air bliss and orange peel, for years. Never thought to use it as strop. My father was an operator (5th SF Green Beret in Vietnam) and always taught me to find things in my environment as tools. All my sharpening stones have come from tile and stone shops in the bay area for free. The ceramic disks you put in the bottom of a vehicles cup holder are excellent for edge touch up.

[@eddy2561]

jdavis882 knows his shit!!

[@annapeterson5897]

This is unreal. I've been using Japanese waterstones. The cool part is there is an Advance Auto within walking distance.

[@reviewsofthings]

Picked this up at AutoZone today for $7.50. Pulled out some dulled Benchmade knives that have 154CM steel. This thing brought back their edge and now they are hair-splitting... about 25 strokes per side. Also used it on some Spyderco S30V blades, but it took a little bit longer to get results. Really liking this stuff. You could even throw a piece of it in your backpack so that you always have a reliable way to re-sharpen. Thanks for sharing this!

[@mistersmith3986]

This sounds great. I know for a fact that sharpening 154 ain't no daisy 🌼

[@billzee-tg8hh]

I have tried this and am now a believer. thank you for sharing this

[@ScottsUtubeWorld]

Great idea! I've been using one of those sandpaper handles because it has foam where you attach the sandpaper (I have a lot of convex blades). It works great with the sticky backed sandpaper. But this would be extremely light, and wouldn't take up much room in the backpack... so I just ordered it from Amazon.

[@KenRadManRaddon]

so did it work to restore that persons headlight?

[@mistersmith3986]

GOOD NEWS:Any sharpining surface with boyency will cause your edge to become convexed after a certain amount of usage. Thanx for the video my Bladed Brother 👍 ⚔️ ✝️ 🇺🇲

[@TylerLL2112]

I been doing this for years.I love it and it works great for my convex edges.

[@poppopscarvinshop]

I use the 5000 "grit" just like a strop, it is Awesome! Thanks Much

[@Keith1983_]

i've always been into knives but just kind of discovered and realized the ''high end'' and actually ''collecting'' so maintenance and sharpening is or has become important thanks i like your videos , i pick up a lot and I'm headed to auto zone right after i type this to get my first strop lol and I'm looking into the edge pro apex 4 , thanks for sharing

[@Dabobeans]

Great video. Love your channels.

[@EliAngwin]

The 3000g sanding foam is meant to be used wet. Paper on a good flat surface also works very well.

[@leebarker4207]

Ok I picked up one of these and 139 people that gives thumbs down did not it works my knife got stupid sharp

[@learner5090]

What are some tips? Thanks

[@shogekimura]

you apologize way too much man you're videos are great much better than the content on tons of other channels

[@VndNvwYvvSvv]

I thought everyone knew this and the mouse pad trick for convexing.

[@hotrodhotrod-wc3bu]

It would have been nice if youd have shown sharpening the damn knife

[@MrMZaccone]

It's not "burnished" it's polished. Two different things. Burnishing compresses surface grain using a harder material, polishing only reduces the surface grain to optical or semi optical quality.

[@Mrsingingdude1]

Not trying to rain but burnishing is the plastic deformation of the edge and comes form objects with similar hardness. When the strop loads with steel dust, it no longer abrades the edge but burnishes the edge against the steel dust

[@MrMZaccone]

Mrsingingdude1 You're correct that burnishing is plastic deformation but plastic deformation requires pressure, more pressure than you get from a strop. It also requires not material of "similar" hardness but significantly greater hardness. It essentially requires the local contact stress to exceeds the yield strength of the material to be burnished. Examples of burnishing tools include polished butcher's steels and the burnishing needles used by Japanese sword polishers. What you have when the strop loads with steel dust is neither polishing nor burnishing but some sort of silly arm-waving bullshit. A strop should be cleaned and reloaded with compound regularly.

[@Mrsingingdude1]

+Edmond Dantez their are actually multiple ways of burnishing an edge. The point being that once this strop loads, it will cease to actually abrade the steel. at that point your burnishing your edge. You dont always need the contact stress to exceed the yield strength to burnish, thats just when the real damage occurs. Since it's been brought up, however, the thickness of the steel at the edge is usually anywhere between .5 to 1 micron thick. at such a relatively low thickness, it's incredibly easy to exceed the yield strength of your edge.

[@MrMZaccone]

Mrsingingdude1 Yes, there are multiple ways to burnish an edge, I named two. Yes, once the strop loads it will cease to abrade the steel but unless you can guarantee that the surface of the old particles on the loaded strop are harder than the new piece on which you're working, it won't do anything else either and we're back to hand waving bullshit. In addition, if those particles are harder, you can't know how they separated from the original piece and therefore, can't guarantee their size and now you're fucking up the polish of your current work. There are only two ways to go as far as I'm concerned. 1. Clean strop, fresh compound. 2. A flat, highly polished, hard surface on which to burnish. Sorry to split hairs but that's kinda the point.

[@Mrsingingdude1]

+Edmond Dantez exactly. I stopped using strops years ago when I realized there's nothing I can do with a strop that I couldn't do with a stone. Point being that a strop is not as good for your edge as a stone

[@WOEShorts]

Awesome stuff! I've been stropping on a piece of 2500 grit sandpaper that I stuck to the back of my wooden strop. Works quite well, but I'll have to try this material out too! Thanks for the share man.

[@robertcallahan1046]

Just tried this and am quite pleased. Does give a nice burnished edge and really improved the cutting ability of the knife. Went from pretty dull to pretty sharp in about 10 passes. Great idea. Thanks for sharing!

[@shadeshiest22]

Where the hell have you been??? Please make some videos, yours were the best knife Vids on KZbin!!! What happened? You alive????

[@jdavis882]

Nick Hall I am! Just not doing videos anymore. Thanks for checking in!

[@leolion1688]

try wetting the sandpaper with water.

[@jv3679]

How do you clean up sandpaper of metal left when done sharpening?

[@PainkillerDCXVI]

Won't this eventually gives you a convex micro bevel? Convex is quite forgiving on angles when it comes to sharpness, but then when you need to actually do some sharpening on a stone you won't reach the edge and gonna have to remove more metal than necessary...

[@asfaltpiloot]

Looks similar to the mousepad with sandpaper trick.

[@BilgePump]

That is some pretty impressive shit though.

[@preferredderreferp]

I have the bark river black, green and white compounds that I use on my knives but I just got a spiderco deli a and don't want to convex the edge. Can I use the green or white compound on a strop without covexing?

[@zleggitt1989]

+preferredderreferp depends on the strop... if its a really hard leather then you strop at the same angle you sharpened at and use medium pressure.. if its softer more pliable then use softer lighter strokes.

[@HelloImDavid1000]

Your wife is very quiet, do you have her on mute mode? Thanks for uploading

[@SunClaw]

Thank you for the great information. I already used it and got great results on my Dozier folding hunter. I will try on all my other knives.

[@specopsbrat5130]

3M also makes 4000 and 5000 grit TRIZACT pads. It's a hell of alot cheaper than that 5 micron green diamond dust compound from Wicked Edge for better results. Napa auto parts is the cheapest I've found. Auto Zone, Pep Boys, are a rip off at like $8 for one 3000 grit foam sheet.

[@jdavis882]

Not high at all, just truth. Their edges are mediocre at best. I've owned 30+ CRK knives, never had one that was even decently sharp from the factory.

[@BRTactical]

Here, in Brazil, its very common to sharp knives with this kindle of material. We don't acess to great sharpening products if we don't buy them for outside our country.

[@MrShtsweak]

Dammit Chelsea!!

[@davidmathews2124]

OMR. That would be the perfect thing to use for convex blades…with the foam backing. I just checked it on Amazon and ordered a sheet. $9! One of the reviews there commented that he used it for a strop and it worked incredibly well. Good find. Thanks.

[@jdisdetermined]

Someone else found my secret! 😱🤐🤫 Knew exactly what this was the second I glanced at it. I do detailing and paint correction, so I use Trizac almost daily. Weird to see my knife hobby collide with my work randomly. You can get all the way from 1000 up to 10k grit pads as well for a beautiful mirror and a stupid sharp edge for very little money. Very small, light and portable system too. Finish by stropping with any gentle metal polish, even like Mother’s or Flitz, (doesn’t have to be that crazy expensive diamond paste) and you have a flawless Rockstead level mirror. I always wet sand so I always use these with a bit of water, instead of dry. They cut smoother and more consistent and it prolongs their life a bit too.

[@learner5090]

So, what grit would you recommend to ReSharper a Japanese knife

[@jdisdetermined]

@@learner5090 Depends on how dull the edge is to start. If it just snags a bit but mostly still slices paper, go with something like 1500. If it’s worse than that, start with 600 grit and work up from there.

[@jdavis882]

Possibly, haven't tested that out. I can make a knife whittle hair using pretty much anything, it's not really about the tool.

[@jdavis882]

Yeah, it's pretty well known that sandpaper is good for edges, but this is something totally different. Regular sandpaper does not act like this. :)

[@azurplex]

Do this on top of glass for flatness for amazing results.

[@rickodonnell2243]

Great tip!

[@jdavis882]

It will work with anything. That's why I showed that it had the ability to cut S110V. If it can cut S110V then it can cut just about any steel you run across.

[@monikaheyman515]

nice job cuts like lightsabre

[@jdavis882]

Yeah definitely if you'd like to convex the edge you can go ahead and apply a fair amount of pressure. Even though I'm not applying pressure it's still micro-convexing the edge, but you wouldn't notice it unless you looked at it under magnification.

[@ozgur937]

6000 grit available too.

[@5118eman]

I just got that sandpaper & you were not kidding that stuff really works thanx...

[@NicholasAarons]

Cool Stuff Dude. 3M Make The Most Amazing Stuff. Keep up the great work. Nick.

[@TheFunnykid33]

works even better when wet

[@SmiTTyy-sh8nc]

This is the best tip I've seen in a long time.... Thanks for sharing this great information 👍

[@jdavis882]

What I consider decently sharp is the ability to cut paper and have some bite. I've never once had an edge from the factory that wasn't over buffed to the point that I could slide it across my skin with considerable force.

[@jdavis882]

Yeah I use trizact belts regularly. :)

[@jdavis882]

I know that burnishing is plastic deformation, essentially smearing of the steel. What I meant is that this sandpaper both cuts the steel, and also has "grab" and pull which I can only imagine is burnishing the edge to some degree which is one reason the edge is so clean straight off the paper. I could be wrong of course, it's happened once before. Haha

[@sickom576]

Lame!!!

[@mistersmith3986]

This would be great for convex knives. I'm getting some. Thanks!

[@robertbefford4190]

Im going to try it thank you

[@briandeines5019]

i think your moma didn't teach you manners . Chelse i didn't hear him say please once.

[@JustRobHere]

I've been using automotive wet/dry sandpaper - 2000 and above - to finish with good results. I make sure it's on a smooth hard surface.

[@JDYTC]

Awesome tip man! Thank you! I guess this will work even better for convex edges right? Would you recommend to press harder when sharpening a convex edge or use the same technique as you showed? Thank you and kind regards from Amsterdam

[@midninteranger4315]

Thank you for sharing, always looking for new and improved ways

[@SteveKluver]

This comes in a 5000 grit as well. 3M (3056)

[@wessonliam7423]

I've been using double sided tape stuck to a ruler with sheets of 1K,2K,3K grit sandpaper. Double sided tap gives the sponginess to compensate for any angle inconsistencies that result from not being a robot. Guess it is time for an upgrade. (that's if I can find it in local stores)

[@davestelling]

Yours is a very good system - the rulers w/ double-sided tape...

[@bwillan]

Won't the foam backing on that sandpaper create a convex edge?

[@davestelling]

My concern, too - but maybe super light passes?

[@jdavis882]

MMmm but where do you reprofile?

[@socomelite1]

C'mon. "never had one that was even decently sharp from the factory" that statement is either rediculous or your expecting laser beams for edges. Every CRK I've had has been sharp as F

[@BruceNitroxpro]

A terrific "find."

[@xxbryan715xx]

my factory edge is horrible. one portion came at about 30 degrees inclusive. the other is at about 50 degrees inclusive. it widens to 50 at about the start of the belly.

[@mlhoward4469]

Nothing new as far as the idea of sharpening goes. 3M developed TRIZACT for that purpose which specifically is polishing and sharpening. It seems OP found it by random chance in a package designed to appeal to the auto rework industry.

[@roy7420]

I love this stuff I use it to polish the washers and to polish the liners.

[@joesquat2891]

i bought one of these and used it after wathing this video my knife could cut paper cleanly but could not do S cut after i passedd 20 times on each side i went to my strop it now S cut very easily i would love to see u do more videos and experiment with this more jdavis

[@jdavis882]

That's exactly what it's for. Has unlimited uses though.

[@dodgedart4sho]

Awesome, I sell commercially for advance auto here in ATL and we carry that. I think its mainly for wet finishing paint. Good vid bro!

[@chipdouglas35]

I need to get myself some of those - thanks for sharing !

[@jbvap]

I have this sandpaper and thought of using it like this but I thought it would round the edge fast so I didnt try. I will have to now

[@BUCKrub91]

i was just thinking that... maybe get another grit for the other side to have a double sideded set for the Wicked Edge

[@jdavis882]

Don't have them anymore. :)

[@vanlurton6068]

I went out and bought some to try it out. It works. I used it to finish my Izula II which was pretty dull when I got it. Now it's a razor. Thanks for the tip!

[@johnruckman2320]

Have you ever used that 3M Trizact sandpaper on curved blades such as a spoon carving knife, tile or rug cutter blade? How moldable is it and what would you use to glue it to a round object?

[@dfailsthemost]

If one has a light enough touch, one can actually feel the bur dragging.

[@skwwtkk]

any hand sharpening method will produce either a beveled or convex edge, the cutting edge of a hollow ground blade is either convex or bevelled depending on how you finish it. the trick to this method is to lightly feather the blade over the paper as you strop to minimize the convexing effect caused by the foam backing. when the final edge has a slight convexing it will maintain its edge longer compared to a beveled edge ( cross sectional shape of a curve is inherently stronger) If a bevel edge is a great concern go to a dental supplier and get a glass mixing slab and glue 3000 grit paper to it. For a pocket knife this foam backed paper is more than adequate if done properly.

[@jaymurphy9127]

thanx for the tip ! I'm gonna try it!

[@JC-fj7oo]

I used to use these to polish my straight razors and one day I got the idea to strop on one. It's a 3k and 5k strop for a couple bucks. And they last forever. Throw one in a kitchen drawer and strop your chef knife instead of using a steel. It's easier and better.

[@CJKrieg24]

Came across this videos and I have seen a good number of your videos and it appears we have similar views in knives, and when watching this and your other videos on the sebenza I wanna ask your thoughts and opinion on the insingo blade shape as opposed to the regular blade shape?

[@jdavis882]

Definitely, you'd just have to do edge trailing strokes only. :)

[@cassanoa]

this is excellent - i saw another tuber that bases his whole sharpening system on different grits of sand paper - it works great and not to expensive - yours is like a sandpaper strop

[@mynineridesshotgun]

Good stuff John. I came across one of these about a year ago while at the auto parts store looking for high grit sandpaper when convexing my BK2. It's great for stropping as you demonstrated. -Chris

[@TheCauscg]

Either way, good idea with the trizact, sorry, should have commented on that instead of trolling on ya bro, lol.

[@simezra]

they have also a 5000 grit and also belts with this stuff :)

[@Xandrosi]

Thanks so much for sharing this!

[@j.shorter4716]

Where did you go???

[@robertttttt716]

You need to look at KZbin videos about scary Sharp method. You will discover this a decade ago.
