One of the main reasons I like whittling is its portability. Most pockets can handle a pocket knife and a piece of small wood. Well I like to whittle small too!
Here's what is in my pocket most of the time:
Knife, strop, piece of wood, and thumb guard.
The pocket knife "scabbard" is oil impregnated leather. This prevents the possibility of moisture caused rust...As you can see, all are "home made".
For public whittling, maybe I should add a sign:
WARNING, OLD MAN AHEAD WITH KNIFE.....
