Denis,

You may find the initial factory edge chips out a little ( very fine) but after sharpening a few times it reduces. Not sure why that is but a lot of others have noticed the same thing.

The mouse pad method takes a bit of skill to master. If you push too hard you can easily fold your edge over or even make the edge round ( thus duller) without noticing. I thought my F1 was a POS that wouldn't take an edge until if figured it was my fault and not the knifes. After a lot of cursing and swearing I got it right and now prefer a convex edge above all others.

Look up a "hoodoo hone" online and it will detail a very good method to sharpen a convex edge as well. Easy to make, works like a charm but best suited to at home bench sharpening depending on how light you like to travel.
