Best way to take wood glue off of tools?
Bucket of hot water and a utility knife is what I use.  Let tool sit in bucket.  Sometimes after a couple minutes you can just touch the glue and it falls apart.  If it is a strong glue it will pop off with the utility knife.  

The hot water is the fastest way I know because it heats both the glue and the tool.  Heating the tool causes its molecules to contract, weakening the bond and the glue just melts most of the time.
