Microbevels, Polished, & Toothy Edges: A Close Up View

This is the very first time I have tried this, so please excuse the poor execution. I will get better at this as time goes on.
I apologize if there is nothing to learn from this video. It was mainly a proof of concept for me, but hopefully you can gain at least something from it. Let me know if this kind of thing interests you guys!

It's the shutter in your camera that phase with your lights ac current at 50 or 60 hz. When your shutter adjusts to the brightness of the blade, the shutter rate possibly start to sync up with the light source in your room. Change to a regular bulb or fix your exposure to a permanent setting on the camera

[@BradGryphonn]

The laser etching by country of manufacture was interesting. I like trivia. Great video by the way.

[@sike8184]

Great video. This has been very helpful in understanding the subtleties of sharpening.

[@Gollammeister]

Wow very nice polish on that micro bevil

[@JDYTC]

I'm learning so much from you! Thank you so much! Kind regards from Amsterdam

[@perspicacity89]

Fantastic. One of your best vids!

[@Caiaiman]

How do you create a micro bevel

[@erichusayn]

Awesome video. Extremely helpful.

[@johnnypea5369]

cool to see the close ups - thanks

[@drumrboy80]

That's cool...I use a magnifying glass, thanks to you, in my sharpening kit. It makes looking for the burr, chips, rolls so much easier..I get better results

[@barkingspider2007]

Nice job 👍

[@illduitmyself]

that wacky light show that flashed showed the microbevel pretty good

[@IronPrayers77]

Maybe try this in a light box/tent, the softer light might work out better or maybe not. Keep em' coming.

[@boombap420]

very cool video. I have a whole new perspective on my edges

[@mbenjamin292]

Wow you really kmow your bevels I listen an watch virtuevoice and you channel poped up great job and thanks for taking the time to teach others howcto do things the correct way.thanks again.

[@falopio67]

after getting the burr in both sides....im doing something wrong...i dont get the really sharp

[@bleish8512]

Hey, thanks for posting this video, this is awesome.

[@patdud1979]

cool vid this is going to give a unique point of view for future knife review good job.

[@elongatuspiranha]

Excellent Excellent Video!

[@CliffStamp]

Yeah the term micro in a lay sense just means small, like the micro-machine toys. However the actual academic/metallurgical use means micron scale. The problem in using a vague definition is that the discussion gets problematic because a micro-bevel which is on the nature of a micron is very different than one which is on the scale of 100 microns (which you can barely see) in how they effect performance/sharpening etc. . Ironically, the name of my channel hints at nano-bevels.

[@pablofcb21]

nice stuff men! you should add a section using the microscope at the cut tests! thanks and keep up the good stuff!

[@TheMotorick]

Your close-ups were pretty good considering. I have to ask, what kind of microscope were you using? I want one. :D

[@5OclockSharp]

@chewy667 Emersons and the sharpmaker don't mix well. I'm guessing your edge veers way off to one direction when cutting through material

[@ezvkm77]

did you upgrade your microscope. If so to what? Great pictures!

[@JamesPettinato]

what magnification are you using

[@oogiesmuncher]

would a 100x magnification be enough to show what i am doing to the edge when sharpening!? or is it not strong enough

[@SnwBrdFrvr]

600? I always assumed the spyderco white ceramic stones were more like 2 or 3000 grit?

[@Peachwhaler26]

Never knew that about the logos, had to look at my delica lol, that is pretty cool

[@OnTheEdge72]

Cool video, very informative =) Thanks for sharing!

[@dennisstrickland5216]

fantastic photos i'm sorry you had problems. dennis

[@warren_delacruz]

12 years late to the party, but thanks for the vid.

[@EverydayOutdoorsNJ]

Very cool!!

[@interista7878]

Nicely done! :)

[@mbenjamin292]

What do you think about Barkriver knifes?

[@pigpaul]

May I please send you my knives to have a edge like this?? You have a website?

[@CTKTMRIDER]

Good stuff !

[@trailtooth1447]

Try playing with colored or polarized filters

[@gundude73]

awesome!

[@mu99ins]

Hmmm...I have some beefs with micro bevels. Start off with, the manufacturers do not specify that they grind such micro bevels, that I know of. How is an owner supposed to sharpen a knife with a bevel he cannot see, and wasn't informed about? It's so small, who is skilled enough to maintain a micro bevel? How would you know if you were accurately maintaining such a bevel without an expensive microscope? Manufacturers are grinding edges that defy maintenance, and fool their customers.

[@saenzgus29]

Sweet. Will help!

[@glytch5]

I don't feel as though micro bevels do give strength... they just make sharpening easy and save metal. My factory edges that have no micro bevels always hold up much longer than after I micro bevel with a sharpmaker. I think I need an edge pro.

[@glytch5]

+ford fairlane well this first comment was over a year ago, I had since bought the edgepro. I generally do them free hand, or if i'm feeling goofy i'll use the sharpmaker. I generally do not micro bevel knives though.

[@gunnuts82]

id like to see a before and after strop vid with the microscope

[@bobmellon]

very cool

[@209chevymon]

so what is better a polished or toothy edge?

[@yolmak1793]

Butchers want a toothy edge, that saws through the meat. That's why they use relatively coarse stones and a coarse butcher steel to create new teeth into the edge.

[@augustwest3575]

cool

[@CliffStamp]

It gets confusing when people refer to a micro-bevel when it is clear that it can be seen by eye. This is common on convex knives which have a v-ground sharpened edge which on a flat ground blade it would be called a secondary or edge bevel. In general edge angles are measured from the center line of the blade, but again that isn't a well accepted standard and some people measure them from the sides of the blade.

[@buriedintheblack]

This looks like a job for 1080p!

[@jdavis882]

@jackchn23 That's the plan! Should be cool. :)

[@kensmith3251]

Is "toothy" just tiny, tiny, tiny "chips"?

[@jacobacostamasterscribe2200]

Ken Smith imagine a serrated knife. Now think of those teeth getting smaller and smaller everything you go up in store grit. So yes in a way. Toothy is like bigger teeth at the apex

[@jdavis882]

@ArtistBlade1972 200x

[@falopio67]

hi

[@MrMZaccone]

Seems to be convex, giving the appearance of a micro-bevel.

[@knivesandstuff]

i like microscopes

[@BennyCFD]

You mean to tell me that this guy can't tell if a knife is sharp without using a USB microscope. 99.9%of people who sharpen a knife can.

[@thefinder8087]

+BennyCFD I don't think anyone told you that.

[@BennyCFD]

LOL...What percentage of people do you think need a microscope to tell them when their knife is sharp after sharpening. Sushi chefs don't, and they work with some of the sharpest knives. I've shaved with my Opinel and Mora just to see if I could do it. Didn't need a microscope.

[@S550GT]

+Nathaniel Graham I think the voice in his head

[@BennyCFD]

I reckon so.

[@HOSSMCGILLICUTTI]

+BennyCFD the advantage of seeing his results using different grits and methods would be pretty handy. Even if you only did it once, you would know how its effects the blade just from memory. There is a big difference between being sharp enough to cut meat, and sharp enough to cut end grain hardwood with a plane.

[@dickmann6506]

Just GREAT!!!

[@bigboss1990]

Keeeeeeeeeeep this up buddy! I love microscopes. You learn so much and its fascinating even if you know what it is

[@gundude73]

awesome!

[@Iives.eIon-tesIa.24]

That is really interesting, nice job!

[@9mmkahr]

i'd imagine a toothy (650) micro bevel would cut better initially but a let's say 6000 grit micro bevel would last a bit longer? i know a micro is much easier to touch up / hone, but does a solid beveled edge, with no micro, last longer?

[@bamafaninky861]

What are you using to view this? Do you know of anything that would connect to a phone to allow you to view? Praying you start making sharpening videos again. RTR?

[@ChristopherSalisburySalz]

I think the lens is trying to auto adjust to the rapidly changing light due to the reflections as you rock the blade.

[@ChristopherSalisburySalz]

It would be interesting to see the blade close up without magnification first and then with magnification so we can get a sense of the edge we are looking at.

[@getredytagetredy]

[@afotsahri]

Thanks for share....GBU

[@X4CTO]

I would personally like to see what you can do to some VG-10 bro... then show us up under the 'scope. I love VG-10, not the best available these days but it certainly has a place in my heart after having performed for me for so many years. Also... I'd love to see some edges after you do your cut tests on the rope, to see what all kinds of micro damage is occurring... I vote for that for sure. Basically anything to give us all some more data and knowledge on the subject is good in my book.

[@X4CTO]

Now you got me over here with my 10x jeweler's loupe seeing what I can see on some of my edges, LMAO! I just sharpened up and stropped my Manix 2 LW in CTS-BD1 and it's a really nice cutter, the edge is not mirror polished but the bevel looks pretty nice and uniform. I for one think it was very cool seeing these things, more, more! HAHA! I've always been the type that liked grabbing my binoculars and magnifying glass and exploring everything. I used to look into my cuts with a loupe too. LOL.

[@JohnGrimsmo]

Awesome vid bud, the only thing I was wishing for was for you to say what angle you were using for the secondary bevel and the microbevel.

[@CliffStamp]

The terms used in discussing knives are not well adopted and everyone tends to use their own preferences. Technically a micro-bevel is another bevel however when switching grits even with clamp/jig systems the stone heights can make small changes in angle so technically you could end up with 3-7 bevels but generally no one would regard them as such as none are visible or intentional.

[@CliffStamp]

A micro-bevel is just that, a bevel which can not be seen by eye, it isn't maintained as such it is simply ignored when sharpening the apex bevel. The blunting of an edge would exceed the extent of the micro-bevel which has to be reset if one is desired when the apex bevel is sharpened.

[@TheDetree]

what magnification are you using?

[@ChuckRichardsHandmadeKnives]

Duuuude, greeaat vid!! Love the info. Nice cam work and polishing. Here's an app that android users can use to see very up close and magnified,,,, it's called "Magnify" in the android mkt, it's free also. Peace out

[@CliffStamp]

Yes, the edge finish should not be confused with the beveling terms, but this is mainly a hobby type discussion so the terms go all over the place. If you check the literature the bevels are very clearly defined, but not every author uses the same definitions either.

[@saintofchelseathomascarlyl5713]

this is beautiful thank you

[@jdavis882]

@pablofcb21 I plan on doing a close up of the edge before and after the test to compare. :)

[@252chevyboyz]

Great video man and I kinda think the flashing of the light really brings out the mirco bevel. Just a thought

[@elongatuspiranha]

I like the Taiwan Spydie the best, pretty cool. Very good info, keep it up. Thanks

[@Den-nu6pv]

Cool

[@jackknifeh]

After using stones to create a toothy edge, how does stropping effect it? Does it refine a toothy edge or round off the teeth which would reduce the "bite" I'd think? The strops I use are cow hide leather wth DMT diamond paste (6 and 1 micron). I also have some horse hide leather strops. It is much harder than the cow. Have you ever done a review of different strop material? Leather types, balsa wood, cardboard, etc. Murray Carter just uses newspaper layed across a stone. Your thoughts?

[@Hexal68]

I've got a question for you. I recently purchased a edge pro system and love it for the most part, but have run into an issue. After I've gotten my bevels and start using finer grits (600 and up), I get little, very obvious, scratches in certain parts. Could this be from my "technique" or perhaps something else? I'm a bit confused as to why this is happening, as I have use other guided systems before (clamp system) and never had this happen. Any insight would be greatly appreciated and if you have done a video on this, please send a link. Thank you.

[@mikesummers8141]

Very informative. I’ve heard of micro-bevels but never owned a knife with one until this week when I bought a cheap Ruike flipper. I looked at the edge with just a strong magnifying glass and didn’t understand what I was seeing until I watched your video. 👍

[@mu99ins]

With what tool would the precision sharpener use to reset the micro-bevel? Yeah, I think calling a toothy edge a micro bevel is incorrect. Basically, isn't it just a toothy edge?

[@holeshothunter5544]

thee blinking on and off is likely an electronic effect in the video cam. Look at where on the blade you are lighting when this happens. I've seen that when the light reflects in 2 directions and confuses the camera.

[@jdavis882]

@TheMotorick It's an Aven Mighty Scope 1.3m :)

[@Evadyn]

Thnx for the vid man. It would be interesting to see some other grinds, a convex or a 0 scandi grind and such.

[@kphifer1]

Once you begin sharpening a knife after purchase/use, how long can/will it take to remove the micro edge?

[@bushcraft_in_the_north]

Hmm, informative! !

[@weaponaficionado]

Very informative. If anyone is confused about how an edge is formed, this vid would explain it.

[@rangodash]

You spent all that time sharpening aus 8 to that degree of sharpness? Wow. I salute you

[@NNNNabeshin]

Nice video, was looging for something like this for a while. Thank you.

[@WhoIsSerafin]

Enjoyable video, that helps me learn what I’m sharpening

[@DJ.1001]

Very well done. IMO one of the most informative videos you have put out.

[@ArtistBlade1972]

What was the magnification level?

[@felecy9]

Staring at that out of focused blue is horrible. The spider would be better.

[@felecy9]

I do like the idea and education though

[@jdavis882]

I’m no pro videographer. :(

[@julietwhiskey01]

Wow! Good information and very interesting! Thanks for posting.

[@Odster661]

Great vid! I definitely enjoyed the micro views.

[@gundude73]

very cool!

[@pablofcb21]

@jdavis882 please! that sure will be awesome!! :)

[@ChristopherSLucas]

Thanks for doing the video It was useful.

[@JNard829]

what did you sharpen that cold steel on?
