Quote:Also recently read on the Fallkniven forum on knifeforums that sharpening a convex edge on a sharpmaker actually 'kills' the convex edge, but I don't know if that counts for the edge on a Sebenza as well. I need to find some good info on how to sharpen a convex edge on a stone.Quote
It doesn't matter who's knife it is, you'll eventually change a convex edge by not sharpening it properly.
There is a lot of info here on how to sharpen a convex edge. Do a search and you'll get all you need.
The most common suggestion is, stropping the blade on sand paper, which is set on top of a computer mouse pad, or any type of spongy surface. The softness of the mouse pad allows it to conform to the blades edge, without having to hold an exact angle.
I took a piece of 2x4 about 8-9 inches long. Cut a mouse pad to fit the top and glued it down. Went to Wal*Mart, in their auto care section you will find wet/dry sand paper in grits up to 2000. All you need to do is, strop the knife, pulling the blade towards you with the edge trailing. A convex edge seems to be the easiest type of edge to care for.
Do a search. You'll find much better info than I can give you, by others with much more experience. However, at least you now have 1 recommendation on how to sharpen a convex edge. It works and is about as cheap to put together than any sharpening system.
