One of the knife makers that I know was willing to share some of his stash with me.
These are some blocks that were old when he bought them 4 years ago.
So.....I think it is safe to say they are dry and ready to use.
Now I need to get them cleaned up and take some photos so I can post them in the store.
I know Randy H will be able to guess what they are, so no telling anyone Randy.
