Thanks for all the nice comments.
The stitch on the sheath is just, I think it's called a rolling stitch, and when I get to the end I just go back the other way creating the x pattern.
I have to confess I may have misunderstood the cheatr knife definition. I made this knife from an old non-carbide tipped saw blade. I cut it out with a dremel (using many tiny blades). When I finished a cut it wasn't even warm to the touch. When I ground it I kept water close by and ground it very slowly to keep it from overheating. It feels like cheating cause it was fairly easy to do and I really like the results.
The thing was pretty hard to put an edge on but it got razor sharp.
