Generally, there shouldn't be blood involved with woodworking. Either you're moving too fast, your tools are dull, or something else is going wrong. Only times I busted a knuckle was when I was rushing and didn't do things properly.

This is especially important if you're working with power tools. A table saw or router injury will leave a big blood stain, so best to correct the issue before that happens.

Is this for wood handling (ie avoiding splinters and sharp edges)? Or for use with rotating machinery? I don't think the latter is advisable.

Get some of those chainmail looking gloves for whittling and stuff.

My old man always told me a job's not done till you've bled on it.
