can someone make understanding grip from tools simpler?

i am having alot of trouble using grip for my sword swinf animation and i was wondering is there a specific wiki article or a special way that you learned to use grip positions from tools

If you're looking for a wiki article, here are a few along this topic.

I don't know too much about tool grips, but I hope this helped!
