Making a convex edge on a hollow ground knife

[TheRunereaper]

Dr Wako, yet another excellent video. I want to buy some sharpening stones and Chosera seem to be the best. The fine grit stones are very pricey and I don't want to make a mistake. Have you tried the round Chosera stones and if so what is your opinion on them compared to the rectangular ones?

It would be very enlightening to hear your opinions on the bigger survival knives although I know you are primarily interested in deer-hunters. Do you have any plans to review such knives? Thanks again.

[virtuovice]

@TheRunereaper I happen to use Chosera #400, #800, #2000 of 3 stones. But the key stone is #400. If you intend to make a convex edge and make a small angled initial edge and make it convex with stropping, you will need 2 stones of #400 and #1000. Chosera is far beyond others. The edge sharpened with the #1000 stone will be fine enough before hard stropping. I have no experience on the round stones. By the way I am satisfied with my Japanese 18cm handy axe for camping and survival chores. Thanks.

[TheRunereaper]

@virtuovice Thanks for the advice. I will go for the 3, as I have already made various strops, so this will give me multiple choices. I get the feeling that you like to do all your convexing by hand, is this because it gives greater control than even a good belt sander or is it the satisfaction of learning hand skills? Many knowledgeable men say that an axe is just as important as a knife. I look forward to your BR Aurora video! Thanks again.

[virtuovice]

@TheRunereaper I have a belt sander and ever used it for convexing a flat bevel knife. Then I used a pretty coarse belt and the edge went burning red and broken off although I paid much attention not to let it do. I will try it again but done by hand is always successful. Thanks.

[damarei]

Fantastic video!

I was just about to message you asking if a hollow ground knife could take a convex edge.

Thanks!

[virtuovice]

@damarei I like a hollow ground knife more than a flat ground knife because it takes a convex edge more easily. Thanks.

[ibrahimhemp]

from which grit stone you considered using before go to black compound ?

thabkyou

[virtuovice]

@ibrahimhemp I happen to use 2k stone before black compound. But I think 1k can be okay. 3k or 4k is good before white compound for a V edge but they are uselessly fine before black compound IMO. Thanks.

[ibrahimhemp]

i have black white and green compound.. which one should i begin with and fnish with?

thankyou



[virtuovice]

@ibrahimhemp I begin with the black compound and finish with the white compound. I don't use the green compound at all because it does nothing for me. Thanks.

[lagook]

wko you no longer use white compound?

[virtuovice]

@lagook I use Bark River black and white compound too. I am just testing the Enkay green compound single use. It seems faster than the black and white compound dual use and the result is the same. So for a while I will use only the Enkay green compound for edge maintenance. Thanks.

[creamneuron]

Hi!

Thank you for your sharpening-videos!

What do you do with the leatherstrop, when the leather is getting dirty after a while? Mine is getting black after some stropping (with green compound) and i am not sure what to do.

Do i have to clean the leather? And how do i do that?

[virtuovice]

@creamneuron I have some types of metal brushes for removing paint. They work pretty well for removing useless compounds. Thanks.

[creamneuron]

@virtuovice Thanks for the answer.

I use the plain side of the leater. The metal brush will not scratch or destroy the leather?

[virtuovice]

@creamneuron No. It makes it even better.

[dullbrass]

@creamneuron do you guys know gavkoo? He cleans his with alcohol in a video; seems to go well.

[Colombiano671]

@TheBladebuster okay thanks:) can i just use the Enkay green compound alone withough having to increase the grit size? or will there be consiquences to taking that shortcut?

[TheBladebuster]

@Colombiano671

Depends on the condition of the edge - if you are just touching up I'd say green compound is enough but it you're getting rid of nicks you will have to use grinding stones or sanding paper - check Virtuovice's other video, he has extensive sharpening videos. I actually learn from him :)

[Colombiano671]

@virtuovice thank you:) im a fan of convex edge and bevel i am trying to switch from v-grind to convex on all my knives. im am looking for the right compounds and leather thank you for your video you convex edge came out beautiful

[Colombiano671]

@virtuovice oh ok thank you and in other words i should definatly invest in blue compound instead of green compound am I correct?:)

[virtuovice]

@Colombiano671 The Enkay blue compound is completely useless for knife sharpening. But for other purposes like mirror polishing I have no experience. Thanks.

[TheBladebuster]

@Colombiano671

Don't bother with blue compound - it was meant for plastic polishing so it will be too fine for steel. To restore a nick I go with sandpaper (grit depends on the extent of the nicks) then go 400, 800, 1000, black compound and finish it off with Enkay's green compound - please note though Enkay's green is not the same grit as DLT's green.

[Colombiano671]

@virtouvice do you think the Enkay Blue compound is necessary for a mirror finish or is the Enkay Green compound good enough for a mirror finish

[virtuovice]

@Colombiano671 I used the Enkay Blue compound just once on the leather strop. Then it didn't make the edge any sharper at all while the blue compound made a razor edge very easily. I guess the blue compound should be applied onto some electric device for mirror finish. Thanks.

[TheBladebuster]

For DLT - go with black and white however if you can find Enkay's Black and Green compound -you're good to go. Google Enkay's polishing compound - they're made in USA. I got it from Princess Auto (Canada). They go for $4.99 per par and should last you a lifetime. I do used sandpaper first before finishing it off with compound like our sensei Wako.

[sgtschmitty8013]

I thought green compound makes your knife duller?

[TheBladebuster]

@sgtschmitty8013

I don't think the Enkay's green compound is the same in grit grade as the DLT green, perhaps closer to DLT's white compound. I've been using the same green compound with very good results. But I will let Virtuovice comment on this since he has used both.

[sgtschmitty8013]

@TheBladebuster Thanks man because, i'm not sure what color compound to buy an what brand to get really sharp knives.

[DiamondLou78]

keep up the great videos! I have seen a "stone flattener" that takes the curve out of worn sharpening stone...diamond material, I tried a dual action palm sander with 40grit that also worked fairly well

[MrBenrokEarth]

@Virtuovice - Hello, when might you review your Bravo 1 in 3V steel?

[virtuovice]

@MrBenrokEarth Very soon. I just finished the other knives I own.

[vjanda1]

@K2Carbides

My answer is found here:

/n_3nAT45bks

Micro convex seems to be about 2-3mm high



[vjanda1]

@K2Carbides

Very interesting video indeed, needs to be watched more than once!

Looking at his chart I conclude that the "thin" convex he's talking about is impossible to achieve on a scandi grind knife while maintaining the original height where the scandi grind starts. Applied to an Enzo Trapper it would reshape the blade so much that it would look take the look of a true convex knife such as a Bark River. Virtuovice does a "micro" convex. I wonder how far from the edge it starts..

[rixcat]

When and why did you switch to Enkay Green compound? Did I miss a video?

[TheBladebuster]

@rixcat

He is testing. I am sure he will do a comparison review soon.

[virtuovice]

@rixcat A friend of mine gifted it to me. And the result can be a bit better than Bark River white compound. Anyway further evaluation will be needed. Thanks.

[Iseekoutthetruth]

Hi, I was wondering if you got that email I sent you of that Helle knife with out a handle on Ebay?

[virtuovice]

@Iseekoutthetruth I got it. But I have never made knife handles and the blade was short for me. Sorry not to respond it.

[TheLateBoyScout]

Outstanding work. That's a real beautiful edge.

[Doggorunning]

great job

[haff202]

Bark River compound black = 3,000 grit

Bark River compound green = 6,000 grit

Bark River compound white = 12,000 grit says DLT Trading



[LMarshall32]

Very well done! Thank you very much!!!!

[jackknife68]

Buy a Dewalt grinder and you'll save a lot of time. You can watch it on my channel, the name of the vid is, how to grind a knife to razorsharpness.

best regards Matt

[seume]

@jackknife68 at first I thought you talking about a angle grinder, I thought there was no way you could get a knife razor sharp with that, I was right you had a belt grinder attachment...lol,,, good video though.

[medogradela]

Are your Opening-The-Box Knives have convex edge?

[virtuovice]

@medogradela No. They still have a factory edge. When the time comes, I will make a convex edge on them. Thanks.

[xxIVANxx13]

nice looking knife, and you sir did a hell of job on that edge ...looks real good i'm now going to try that myself,,

[Ievgen1985]

O-lo-lo.

Very nice work on the stones.

[mikedifeo]

Great video. I like the low angle edge. I use it on most of my knives, spceially the smller folders and fixed blades.

Where did your get the stroping blocks?

[virtuovice]

@mikedifeo From Crystal Falls Trading > Bark River > Sharpeners. Thanks.

[wigglos]

how do you clean your strops when the leather is saturated with compound and metal particals? do you just scrape it off, or do you use another method?

thank you

[virtuovice]

@wigglos I use metal brush for removing paint. Thanks.

[Iseekoutthetruth]

lol Mc Donalds is very bad food to eat. I lived in Indonesia for 3 years and they also think McDonadls is a great place, also I have not heard of the American Gladiators since the 90's wow that was a good show to watch. I like American Ninja show better tho

[rifle22coach]

Could you have did this with sandpaper?

[virtuovice]

@rifle22coach Yes. I can do the same thing with sandpapers. But I hate dust from them.

[vjanda1]

I know you are a big fan of the convex edge.

Do you think Mora scandi grind knives would benefit from convex edge?

Is it possible to convex such knives at all?

Thank you !

[TheSchnozwanger]

@vjanda1 You can't really convex a scandi grind that would just round the edge and make it dull.

[vjanda1]

@TheSchnozwanger

He seems to do that on his Enzo Trapper which is a classical scandi grind...

I can't imagine how that works :(

[mz9393mz]

@vjanda1 It works fantastically well. Try it and you won't have to imagine.

[mz9393mz]

@TheSchnozwanger It dulls the edge just enough to make it strong enough not to roll and chip, as Scandi edges are wont to do when cutting hard materials. I have read or seen in videos Scandi knife makers say that using a convex micro-bevel on their knives is a longstanding tradition. I do not know if this is true, but it seems to make sense, considering how practical it is to use such geometry.

[wigglos]

@vjanda1 all his nordic knives (karesuando, enzo, ...) have a convexed edge bevel, you can look up those videos on his channel

[vjanda1]

@wigglos

I'm trying to picture it in my mind but I can't :(

A scandi grind is a straight V.

Wouldn't trying to convex it just make it dull like TheSchnozwanger remarked?

Maybe he's applying a super duper micro fine convex I don't know...

[mz9393mz]

@vjanda1 Yes it would technically dull the edge, but only infinitesimally so. What you gain in edge strength and ease of sharpening far outweighs any dulling you might get in making Scandi edge convex.

[virtuovice]

@vjanda1 I always put a micro convex bevel which height is 3mm or so onto a Scandi grind knife in order to add strength against hard materials on its edge. But if I made a convex bevel from the same starting line, it would certainly make the edge angle much larger and duller. Thanks.

[donnya1000]

I often wondered how you did this. I will attempt this now that it is clear to me. Very good instruction!

[jambiyaSlaughter]

Wako, why are you smarter than me? I can't do that stuff. Japanese people are better than Americans. I hate myself and country.

[vjanda1]

@jambiyaSlaughter

Despair not, you have McDonalds and American Gladiators !

[edwdixon5]

@vjanda1 He's not American, idiot.

[vjanda1]

@edwdixon5

Learn to read before you comment twat face.

The comment was not directed at virtuovice.

[edwdixon5]

@vjanda1 You're as dumb as you are ignorant, and in person I'd have you pissing your pants with a look. I know who the comment was directed to, moron. And I doubt you'd know what a twat looked like in any case.

[vjanda1]

@edwdixon5

I know your mamas one needs a good wash as it surely reeks of the hordes of drunken lowlife and truck drivers that shot her up full of dead semen that miraculously produced you.

I'd snap your pussy yankee spine like a rotten twig and then shit on your face just as drew your last breath.

[edwdixon5]

@vjanda1 Okay, virgin. Now I'm scared.

[MPSecare]

Griptillliiiaannnn!!!!

[RedneckInCarolina]

Thankyou

[CharlieThePuffBall]

superb video!



[AussieMark909]

Great instructional video. Thanks Wako.

[AsdrubandanzIII]

Thank you Wako, this is very useful.

[kofata5]

Is it possible to sharpen convex edge with Edge Pro or edge pro is only for V Grind edges?

Nice channel and great videos!!!

[BulletCastDuo]

@kofata5 as far as i know Edge Pro is only for v grinds ...

[baggedandblown]

Very nice work on the stones. I think it would require a lot more finesse getting a nice edge on a stone over my budget sandpaper sharpening setup.

[ibrahimhemp]

why did u use green compound instead of white for finish strop

[virtuovice]

@ibrahimhemp The green compound was made by ENKAY in the US. I was trying it and the result was pretty good. Thanks.

[stefanwolf88]

I don't think convexing the V-edge on 110 hunter is a good thing - the angle from the factory is 22 degree - it's shalow enough for the soft 420HC steel - perhaps you must try 110 with new edge on a deer to chek for chipings or edge problems in getting back straps. Anyhow - great reprofiling job - when I convexed edges i use sandpapers, not a stones.

Stay Safe!

[handsomewood1]

@stefanwolf88 I have convexed many Buck knives with edges thinner than the m110. I just convexed a Vantage in 420 HC the other day and it cuts MUCH better. Unless you are going to batton wood with blades those size, the edges that Virtuovice is cutting on those blades work very well for cutting. Many of the buck edges are much more blunt than they claim and are not very shape out of the box. The convex micro bevel is great on these blades.!!!!!!!!!

[virtuovice]

@stefanwolf88 I used it on deer in new condition. It was very sharp and didn't take any chipping. Anyway its factory edge angle was pretty shallow as you say. Thanks.

[PainSorrowFury]

Cool Rat 1 :) I've got one but with the regular black handles, didn't need to stone sharpen it yet, because it has a very sharp factory edge. Just stropped it with white compound :) Keep up the good videos!
