Kevin,
That sounds like a good idea.
While you have the scales off of it, I would knock the guard off as well.
There used to be a leather supply shop in Spokane where we bought a lot of hardware and supplies. Besides Tandy. IIRC, it might have been associated with Leather Factory? Of course, that was 16+ years ago, so things could have changed.
Yep, the CdAML club does like it's knife throwing. Always a sure fire way for me to lose points in the aggregate. I was pretty fair with tomahawks, but the knives just pulled me under. Ugh!
As a comparison, the Hawken Shop throwing knife retails for $60.00+, so you are ahead of the game, assuming yours works out.
Remember, while the tomahawk will usually stick with one turn in 6 paces, that is not always the case for a knife. I have had my best luck throwing the hawk first, then stepping forward one pace and let go with the knife. YMMV.
