It’s up to you. There’s a traditional wooden drinking cup called a kuksa that is popular with outdoors types. It’s carved from a solid block of wood. You can buy them, but it’s more “bushcrafty” if you make one yourself. Further, you’re supposed to use only hand tools, no power tools. OTOH, one that you order online was probably milled by a machine. It’s hard to tell them apart though.

Is there a philosophical difference? Up to you.
