How to sharpen a knife (Convex edge)

[triggerhpy]

R U a scout?

[fluffatronix]

no wood gas or stove then nil poi !

[wakey87]

I never new those type of knives have a convex edge, personly i dont like them for various reason but for the price i admit they probably can't be beat.

[bac2397]

boo



[rjsahadi]

This is a perfect example of why KIDS should not try to make videos.

[TheChalkychalk]

gungravel123 he could dry shave you with that blade. Thanks for the tips on the video.

[mainetrapper]

do all opinel knifes have a convex edge, because i bought one to day and i'm pretty sure that it has a chisel edge on it, and how thick is yours, it looks to be a good deal thicker than mine.

[leonardo1480]

the foam you used would it not be best to glue down and a peace of scrap wood?

[Urudrim]

that's a nice, no-frills folder you got there.

[Grungadin]

I usually hate folders but that's a nice looking knife.

[Rattlehead942]

Dude staple that sand paper down don't risk your fingers

[kingboru121]

this was a very interesting vid your idea on the backing you use is interesting and you clearly put a sharp edge on the blade. Ive put a few years into sharpening and found it seriously frustrating at the beginning because of the lack of knowledge so for you to be able to know all this is impressive at your age. The only thing i could see wrong was the impatient strokes in your technique. Maybe slower is better only for me though

[Gungrave123]

Still laughing. How to ruin a knife is the correct name for this video

[MaxPayne725]

@Gungrave123 Clearly it is sharp at the end.

[DWGTI]

Well done wee man. Good vid

[Thetruthishere11]

not convex sharpening.  but good vid. you can use hardcardboard instead of strop.

[nightwalker2830]

can u shave with your knife i seen murray carter shave with his after sharpening it

[75SilentWarrior]

He shaved a little in the video at the very end.

[86thmountmerrion]

@nightwalker2830 Yeah generally after I sharpen, my knives will shave hair

The way Murray Carter sharpens his knife is designed to give you a very fine edge which is useful for food prep and cutting items such as rope

The way I do it is good for wood carving and other tasks you would need a "toothed edge" on the knife!

[BigDumbJerk]

Murrays hollow ground will out perform your Convex "toothed edge" in any task. Even wood carving.

[75SilentWarrior]

@BigDumbJerk Murray Carter puts a flat edge, and has been doing so for 25-30 years. I would hope he could do better.

[BigDumbJerk]

Do better? Hes a Master smith. If you don't know what that is I suggest you look it up. I purchased a Carter knife and it out performed everything I had. After I used his sharpening technique It out cut my Bark river shit knife. Sorry but you have no idea what you're talking about kid.

[75SilentWarrior]

@BigDumbJerk I meant better then the kid in the video. Dumbass.

[BigDumbJerk]

Maybe try some grammar then, Dumbass

[Dersabom]

lol i hav NO idea what the comments mean. no offence but please dont use the "big" words. THIS IS NOT AN INSULT!!! dont get mad i just would like you guys to help fill the less educated of of us in

[perchjerk]

One of the biggest mistakes pple make is with pressure. Usually the weight of the knife is enough to do the job. An excess of pressure will actaully dull your edge by rounding it off. Ive found that the tip to heel method works much better in ensuring the tip is as sharp as possible. when you let it run off the pad like u did you are dulling the tip.the edge should stay perpendicular witht he hone. like i said, if your works, then cool. just trying to enhance your knowledge on sharpening.

[86thmountmerrion]

I agree and I like to only use the tip to heel method on a mouse pad because a mouse pad isn't very dense but the foam I'm using is very dense which you can't properly see in the video so extra pressure is needed but the foam will still maintain structural integrity and not roll the edge so when sharpening the tip by lifting it as you would on a regular stone you roll the edge so by keeping the edge flat to the very dense foam you can maintain a keen edge on the curvature and tip of the knife!

[perchjerk]

Like i said, if it is working for you, great! Im only trying to further you knowledge of knives. Im not a pro by any means and this is just my opinion..but.. my opinion is constructed from knowledge i have aquirred from those who are professionals and my sharpening results have drastically improved. Just keep looking for better ways to hone your techniques even if you are getting good results. never hurts to learn more! thanks for the reply!

[75SilentWarrior]

@perchjerk If your edge is perpendicular to the hone that would mean you were dragging the edge itself straight down ther hone.

[perchjerk]

Good vid. Great to see young ppl becoming enthusiasts. BUT...you do seem young so its important for you to keep an open mind. There are others who have been doing this alot longer. As others have said you technique is a bit off. Ppl do thing differently and if it works for you then great. But i assure you if you follow certain techniques that are more proper for maintaining a convex edge you will have even greater results.

[86thmountmerrion]

If you are referring to the comment down bellow we continued that conversation in PMs and it was clear that he had no clue about what he was talking about by saying that you should never use anything other than a flat surface under your knife and that that blade must never lift off the strop and always turn the blade on the spine of the knife....but what techniques am I missing out on?

I'd love for you to help me out!

[johnjayrambo11111]

i love those opinels ,mate great video .

malc

[Conan568]

Great video kid.

And you were right too.

I convex grind all of my blades to some degree.

[derikgrebner87]

No point in trying to show or tell this kid anyhing. I tried, but it appears he already knows everything. You'd think that after 30 years of making knives, I could help him, but oh nooooooo, not this guy, at 10 or 12 years old he already knows everything there is to know about knives. Can't wait to see his gun reviews.

[86thmountmerrion]

Okay I'm not trying to argue with you or be aggressive but all I'm trying to say is that I'm not doing it wrong. If you want I can make a video explaining exactly what I'm doing because the camera angle on this video is hard to show what I'm doing properly. Lets not fight there is no point to it,Youtube is just for fun...I'm only trying to educate people here!

[75SilentWarrior]

When you say your knife is not the normal shape it's because you are not supposed to use a honing rod on a convex edge it will flatten it.

[derikgrebner87]

Jesus Christ another fucking know-it-all 12 year old.

[86thmountmerrion]

Thank you for your input and comment.

[derikgrebner87]

At 8:07 or so when you're "stopping" the knife? You're rolling the knife over onto the sharp edge. That's the wrong way so. Watch a brber stop a blade and you'll notice that he pulls the blade AWAY from the edge and rolls it over on the BACK of the knife. You are rolling the knife over on the SHARP edge. I hope that helps you a but.

[remoc8116]

Great Job, You sound pretty young, Are you a knife enthusiast?

[75SilentWarrior]

Could you use this on a standard ground blade as well? Awesome video.

[metaphysikz101]

awesome work! really enjoyed the vid and hope ya keep putting out educational stuff like this :)

[canteencorner]

Nicely Done!

[86thmountmerrion]

Thank you!

[Slic3R1]

i've used this method too some time ago and it is really good for sharpening all kinds of edges and for a precise sharpening

[icychap]

Great video. Thanks so much for sharing your technique. Do you advice using this process for a larger, fixed blade knife with a factory "V" edge? I am thinking of convexing the edge on my Trail Master and would consider this technique. If so, what grits should I use (beginning to end)?

Thanks!

[86thmountmerrion]

This process will work fine for any knife and I would recommend that you start with 180 grit and work your way up to about 1200 grit!

[drunkfux1]

What grit wet and dry is that? and what do you call that stick you use? is that to take the burr off? can I use anything else like a belt? or my jeans to take the burr off?

[86thmountmerrion]

You can use as low as 250 grit for rough work and as high as 2500 grit for super fine work!The rod is just a ceramic rod but thats not essential you can get the same results with some 2500 grit paper!And for a strop you can also use a few sheets of news paper because I've heard that the ink is abrasive and you can also use flat wood or M.D.F but it helps if you have some stropping compound on it!

[drunkfux1]

thanks for the help mate

[drunkfux1]

Great vid, very helpful

[86thmountmerrion]

Thank you!

[888zzz]

How does this convex sharpening method differ from sharpening a Scandinavian ground blade with no change of angle at the edge? Are the methods the same except with a Scandinavian edge a harder surface is used so it doesn't form around the edge creating a convex shape but stays flat?

[86thmountmerrion]

It is similar but by sharpening this way you will not retain a flat grind it will have rounded over into a beveled convex edge unless you were to put a piece of glass underneath the sandpaper which would keep your edge flat and still have your scandi grind.

Hope this helps!!!

[captcarl2]

Also, nice to see a young person who isn't all into fancy tactical knives. I'm young too and I think the traditional ones and slipjoints are the best!

[86thmountmerrion]

Yeah I totally agree I like knives for practical use not just for good looks!!!

[sredge1]

i think your irish like i am (dublin maybe?) an i was just wondering where you got your opinel because i cant find anywhere in dublin that sells them(i dont wanna buy online)

[86thmountmerrion]

I'd recommend you go to army bargains or millets.If you go to the coast and search around in any fishing related shop you should be able to find one for about 12 euro and also don't forget that "un carbone" has to be written on the handle written in black for the blade to be carbon steel.

Hope this helps.

[captcarl2]

Nice knife. Put some mineral oil in that pivot though. It looks pretty dry. My opinel opens and closes like butter.

[86thmountmerrion]

Thanks for the tip,The pivot is clean just black because I've had it for a few years and the knife opens smooth enough but with season wood movement it changes every year but I keep it oiled and it works great!!!

[capreolus4]

thanks for posting.hope many more to come.learned a lot.

[86thmountmerrion]

Thanks and I should have another sharpening video today!!!

[LovePup1017]

Swuch eh English auceccent LOl

[86thmountmerrion]

What do you mean???

[LovePup1017]

what i said is

"Such a English accent." lol

[86thmountmerrion]

No I don't!!!

[LovePup1017]

well irish accent!

Whateva

[86thmountmerrion]

Big difference!!!

[madcow1001NL]

he

good vid

only one thing. when using your strop, you have to keep the blade level (flat on the leather) stroke it backwards stop then lift it up. Otherwise your round the edge and make it dull.

[86thmountmerrion]

That is true but it it doesn't really apply to strops that are on flat boards because the leather can't curve around the edge but you are very right and well done for pointing that out!!!

[madcow1001NL]

what I meant was that when you end you stroke you "roll" the edge of the blade. This has the same effect when using a belt strop.

[86thmountmerrion]

In the video it is hard to see but I don't roll the blade it just looks like that as I lift it but you can see that I lift it off the leather so the edge doesn't touch the leather but I do it too fast to see properly!!!

[MrBillTroop73]

Good Job!

Check out a website by Japan Woodworker. I used to work there a couple of years agol

You'll love it!

Bill

[86thmountmerrion]

Thanks and I checked out that website and it's packed full of cool stuff,I've payed about double for the exact same stuff in different shops.

Thanks for the support and recommendation!!!

[MrBillTroop73]

In the 6 years I worked there, I purchased a lot of stuff from there.

Talk about spending my whole paycheck!

LOL

Bill

[86thmountmerrion]

But I suppose you can justify all your purchases by saying to yourself "I really need it" or "it's a bargain".......lol

[MrBillTroop73]

Yeah, that, and, "someday I could use this!"

LOL

[86thmountmerrion]

I don't know how many times I have bought things impulsively whilst saying that to myself!!!

[wildlifeed]

Great job!! What was the book's title again? Gotta get one!! Ed 5/5 and fav

[86thmountmerrion]

Thanks and the books title was Bushcraft by Mors Kochanski!!!

[FriarTuck1961]

Excellent video!

Thanks

[86thmountmerrion]

Thank you!!!

[jackaj545]
