This helps me explain to my customers why they are having a hard time maintaining their flat bevel edges. They are skipping the first step of the large bevel and going straight to the smaller bevel on the edge. The more they sharpen the smaller bevel without dealing with the larger one, the less effective it gets. I may have to make some wooden models. Thank you.
Instead of instructing on how to sharpen Bark River convex blade angles, with a succession of flat grinds...how about correctly informing on the angle that Bark River uses on a BELT sharpener to properly create these edges...for the people who have a belt sharpener and seek to maintain the edge as Bark River created it ?! I don't want to hear how to modify a Bark River convex edge, because all some person may have is flat grinding equipment.
I don't agree at all. NEVER use anything soft. If you don't know how to properly sharpen a convex edge on a stone (sandpepers glued or pined on wood or any hard surface, also works) then don't try to sharpen that knife at all. Soft materials not only provide uneven edges, but also the edge angle and the amount of convexing, will change so much, that you will destroy, any knife that you try that method on. Sharpening a knife, is 70% experience, 20% knowledge and 10% tools.
PS The more times you sharpen the wrong way (soft surface) the more the damage you do to your knife. Knives edges and also their bevels and geometries, should be perfect and even. The method that is shown here, is VERY wrong, especially long term.

Dude this video is extremely helpful, the visuals of the thermarest and convex edge are spot-on. Thanks for posting.
An intelligent, well prepared and presented video. Thank you.
never seen anyone use a wood block cut to match an edge demonstrate the edge, very cool.
Derrick, thanks so much for putting these up and sharing these!

You’ve helped understand the concept. Thanks.
Awesome information.
Great teacher, demo. Now I really get convex vs flat:).
Well done. Thanks
Very nice. Thanks for sharing.

I just thought this is common sense. But I guess not. As the saying goes. Common sense isn't so common
