Convex grind: AMAZING!

That's it, I can't hang around here, I'm too vulnerable. I'm going out to test my new Silky Saw in a NYC park (there was a storm here several weeks ago that knocked down a lot of big trees and the parks department hasn't caught up :D)

I have many (many) other knives and none of them can compare in cutting prowess against my Barkies. I can't wait til the Gunny comes out (drool).
 
Bark River makes a hellavu knife for the money. I have a Northstar, Woodland Special and a Micro. I heard they have a replacement for the PSK I would like to check out.

Buzzbait is (was) a forumite that did some great testing on convex grinds several years ago - worth digging up an reading.
 
That reminds me. My woodland will be celebrating its 5th bityhday next month! I think I need to get it a younger (but bigger) brother.

I'm thinkin' Snowy River. Any opinions on this one?

My first Bark River was the Rogue. The funny thing about the convex edge is that it's so effective that this really big blade worked great as a kitchen knife for paring, for slicing & dicing, and (of course) on watermelons. :D

Not only is the convex edge sharp it is in accordance with nature. Mankind thinks up things like bevel angles and other nonsense. Nature abhors straight lines and is all about curves.

There are different styles of convex edges. I've put a convex secondary bevel on flat and hollow ground blades. It's a big improvement. There are knives with flat grinds that come to a zero edge which is close to a convex edge and can easily be converted to one.

But Bark River uses a full convex which begins curving from the top of the generally full primary grind and curves progressively toward the edge. I know they do this by hand but I wonder if you averaged the curves they produce like this, you'd find the same mathematics as the Fibonacci series, which approximates the golden ratio 1.618034.
 
I just got a bark river PSK in trade, I havent recieved it yet, but it is ment to replace my EDC. It will be my first barkie, I hope it lives up to my expectations, and it looks like it will.....
 
The convex is awesome! Once you learn to maintain them, they are very easy to maintain. Brian I cut my thumb almost the same way cutting free hanging hair, it hurt like crazy.
 
I have moved to a gauze/tape combo because I was bleeding through the double band-aid treatment. LOL. Wow! :D
 
Yep, I will be getting set up to convex all my blades soon, lots of sandpaper and all that.
I wonder if I can use my lansky system at the right angle to get that initial shoulder off.
Then I guess it will be only bark rivers to buy!:D
 
Still yet to experience a convex blade. Soon I'll the Gossman PSK and can't wait for the BRKT Gunny as well!

I hope your thumb grows back okay.
 
Brian right through the finger nail. That HAD to hurt. It might be time to add another Barkie to my collection. Heal quickly.
 
Hey guys how do you keep your convex knives sharp in the field?

How would one keep a convex sharp if one didn't have sandpaper, mousepad, cardboard, or a compound impregnated leather strop? In other words...in primative situation with minimal tools/supplies?
 
Looks painful brian! I hate stuff under/near the fingernail. Hope it heals quickly for you!

I remember my first convex, a gent thinned out the blade on my Tora with a belt sander. I couldn't believe how it sliced when I got it, it would shave hairs off with less effort than a razor. If I was better at maintaining them, I'd have most all my blades with a convex edge.

You could use your pants, if its tough, but if your naked, you could sharpen it on a stone, but it's not easy if you had no practice.

I apologize for the grammar.
 
The only thing I dislike about knives with a convex grind is that I'm not very good at sharpening them. I have been using my Sharpmaker for years to sharpen all my knives and the sandpaper/mousepad technique has been tough for me to pick up.

I've tried every trick in the book and am still only able to keep a moderate edge on my convex blades. I've been patient without too much success.

One thing that has worked, however, is to dump the mousepad. The mousepad made it worse usually (I know, 'I'm pressing too hard and rounding the edge'. It still does it with a feather touch.). I just take some X grit sandpaper and lay it on a hardback book, then drag spine-first with the weight of the blade, at an angle where the edge is just *barely* touching, if at all.
