Swivel Knife Exercise

Here's a swivel knife exercise that I recently came across. It's for those of us who need a little practice cutting graceful curves and ending short cuts nicely. I got it from the September 1998 (old!) Rawhide Gazette (put out by the PSLAC). Though it seems as though it's a waste of leather to practice it very often (like every day?), it wouldn't hurt to learn how to perform those finishing touches!
