I've been meaning to try the mouse-pad/sandpaper thing, but the only knives I had with full-convex grinds were a BRK&T Mini-Canadian and Highland, and I ended up trading them both away. Nice knives, very sharp, but much smaller than they look in pictures, heavy for their size, and the full untapered tangs made even the Highland a little handle-heavy... and the Mini weighed more than some useful knives I have that are twice it's size. Also not quite enough point for my taste (I think Mike said they're changing the point on the Highland after the first production run), but, mostly, the handles were just a bit small for my hand.

I still have high hopes for the North Star, though. We'll see.
