But all kidding aside, there are lots of whittling techniques that come into play when whittling the Morel mushroom. The three cuts below are probably the most useful.
For a right handed whittler, grasp the wood in the left hand, place the thumb of that hand against the thumb of the right hand holding the knife.Next, pivot or lever the knife towards you, working against the right thumb. With a little pressure from the thumb on your left hand against the thumb on the right hand, while levering the knife to make the cut, it will provide a lot of control.
To whittle away from you, place the left thumb against the tang or back of the knife blade, and lever or pivot the blade into the wood to make the cut.
Seems to me that whittling mushrooms does provide worthwhile practice with the knife. It doesn't make any difference about the size of the whittled mushroom either.
And of course I'll use these little mushrooms in scenes like the gnome and the flying pig.
