This knife is perfect for carving the shrink cup in my last instructable
Step 1: Tools needed
You need a hammer, a saw, a file, a vice, an ax and a knife.
I also use a froe and a metal ruler that is nice to have but you can do with out them.
If you don't have a froe use a big knife or a ax to split the wood.
And as a substituted for a metal ruler use the backside of a saw.
