Worksharp--worth it?

I have sharpened for a long time and use the best of stones, it allows me to sharpen very quickly.

So let me get this straight.... you can take a folder that's made of decent steel -- say a ZT in S30V -- reprofile it down from 25degrees to 20degrees
and put a mirror shine on it in under a half-hour?* With waterstones?* I honestly wouldn't have thought it possible.

Most of us couldnt do that. However, if you look through Jason's posts, you'll find he's very talented at putting on edges, and far from typical in abilities.
 
The term convex edge is hype. A convex edge adds nothing to the way a knife cuts. All things being equal, a flat ground edge will cut better than a convex edge inside the same dimensions. Its the technique used in making an edge convex that adds to the sharpness of an edge; its not the shape itself.
True flat edges are harder to produce than convex edges because, any deviation from the desired angle, when sharpening, will alter the apex. With a convex edge technique being used, this problem does not arise. The apex is always being contacted.

Convex edges are fine, there is nothing wrong with them at all other than the fact that they are never the same; they change as different pressures are applied against the abrasive being used.

A flat ground edge, on the other hand, can be reproduced over and over with out deviation from there norm if a proper technique is used.

PS If a convex edge goes half way up the primary bevel everything written above is moot.
 
I borrowed a buddy's work sharp yesterday to put edges on a few blades I made. They came out shave sharp.

I tried to do them by hand and I could not get an edge at all.

I'll definitely be buying one soon.
