Mine 2 Large stones. Use Meat Tenderizer (only tool) to make Sharpening Stones. Only produces 1.

It is super hard to find these and I know it is a problem for almost everyone. Would allow players to craft these so there would be no need to have them as a respawn item anymore. Would also decrease the need to readd other items in the game as well. Items that could be resharpened would be all knives, pickaxe, sledgehammer, hatchets.
