Fletching Table Purpose: Making Flint

By putting the following into a fletching table, you could have a 50% chance (gravel and coarse dirt), a 15% chance (overworld materials excluding gravel), a 33% chance (dripstone), or a 25% chance (nether materials) to get a piece of flint:

Gravel, diorite, granite, andesite, basalt, smooth basalt, blackstone, gilded blackstone, deepslate, dripstone, coarse dirt

As a plus, putting gilded blackstone into the table has a 33% chance to give you 1-3 golden nuggets.

If you don’t get flint or gold, you obviously get nothing.
