I sharpen tip first because I can get the tip sharper than I can by using the heel first method. Could never really get the tip sharp that way.

@scarz1951

That is why I switched too. I can now go both ways but tip first works really well.

what is a convex edge

[NechakoRiver]

@Mistarfrio

It is a smooth grind that curves right down to the edge and doesn't have a flat bevel. Convex knives cut really well and I have found that the edge lasts longer.

Sweet, I just bought a leather strop, and some compound stuff, I plan on sharpening my Cold Steel Spike. Thanks for the info.

[NechakoRiver]

@nsw1535

Yes, I have done it a few times.

@NechakoRiver

Alright cool, I'll check that out. Do you thing you could wittle hair with it?

[NechakoRiver]

@nsw1535

It will shave easily. Check out my other video for a demo of a complete sharpening.

How sharp does this normally get your knife when your done with the green?

[NechakoRiver]

No problem :)

[LaughingFlame]

Good, succinct, helpful video. Thanks!

[NechakoRiver]

Check out my other videos, I show a full sharpening with sandpaper and a strop.

[drunkfux1]

Good vid, but is this just to hone the knife? What if it needs a decent amount of sharpening? Wet and dry paper?

[NechakoRiver]

It works, check out my other videos.

I have a small rectangular piece of mouse pad and sand paper that I can use to sharpen while out in the woods.

I have found convex blades hold an edge better than other grinds so I wouldn't worry about it.

[Bokkenlover]

I'm been thinking about convexing one of my blades but how do you sharpening them out in the field? i carry a small sharpening stone when I'm hiking I use that a fair bit.

[NechakoRiver]

I just work through various grits of sandpaper.

I have accidentally hit a rock before and put a good size ding in the blade. I used some coarse sandpaper to fix it.

If you are having problems with chips maybe try a thicker more supported edge.

[ritter89]

I do this, as well. However, I was also referring to instances when the blade isn't merely dulled but actually chipped. In those cases I either use a DMT stone and 'try' to mimic the rolling motion (doesn't often work) or simply use the slack portion of a belt sander. Problem is that belt sanders generate far too much heat, at times.

You use sandpaper in all instances, even for grinding? How? I tried doing that a few times but it tore the sand paper and took hours to simply form a bur.

[NechakoRiver]

I use sandpaper and a mouse pad if the knives get really dull.

If you look at my channel I have a video about using the sandpaper to sharpen.

[ritter89]

Yes, but what if you use your knives constantly and are rough on them, and yet would like to maintain the convex grind without regrinding or bringing it to a belt sander? I wood carve mostly with knives that have convex edges. I don't often grind them myself but have them professionally ground. Problem is that these edges, although long lasting and durable, do eventually become dull and need something more than a simple strop. What to do then? Or perhaps if they get chipped?

[NechakoRiver]

Lee Valley sells them but I can't remember how much it was.

[yeppyea]

where can you buy those leather strops like yours and how much did it cost?

Thanks
