I was cleaning out my garage and found my old woodworking tools tucked away. So I got the itch to whittle something, but of course the knives were dull. After some time on the belt sander and leather strop, I got the knife to 'shave' arm hair. I ended up whittling a ball-in-cage. Turned out pretty neat. First question everyone asks is, "How did you get the ball in there?". They are then impressed that it was carved from a single block of wood with only a knife. It seems like a lost art gone by the ways of technology and mass production.
Reason I ask, is that it seemed like a great 'recovery' exercise after a hard workout to get the blood flowing, increase dexterity and to produce something neat.
I don't have an actual picture of mine, but here's what I'm talking about.
