Well, Bawanna. I been playing with this website like you suggested and I believe getting to know it is akin to making a wooden sheath. Guess I was too used to the old format. You might want to try some poplar wood. It's not expensive and is what most non-professional (read Bookie here) katana makers use for their sayas & tsukas (if they do not buy a tailor made). I find it easy to work with, light, and pretty strong/tough. If I can do both, anyone ought to be able to carve out a khuk cover.
