When I was little, I used to work with my dad on the engine of his car. Mostly this was a matter of me handing him wrenches.
A molcajete is a stone mortar and pestle from Mexico. They're great for grinding spices and making salsa and guacamole because they give everything a nice coarse and rustic feel. I've never collected anything, but I think I might start collecting these because each one is decorated differently.
