Amals, me as well. Never had to mess with convex until I got my WarDog.

Yes, a LOT of people use the mousepad/sandpaper and leather method for sharpening and maintaining their blades. I never have. I've always used the regular V Grind and have never felt cheated. That sharpener is made of brass and the rod is screwed into the "Handle" for storage and of course removed and inserted with the rod out for use. It's a strong unit.
