When you get your ZT0350, try to find one of the small, round ceramic rods to use for sharpening. You can hold it in your fingers and CAREFULLY keep the edge on the 0350 sharp as a razor. Like I said though...CAREFULLY!! I have one that:s about 5" long and it works great (I do wish that it was about 2" longer though). The recurved blade is so much easier to maintain with the rod as opposed to a flat stone.
