A less tedious way to get flint. (Chert Blocks)

It is always monotonous breaking and placing gravel repeatedly to get flint early game. Honestly, It would make sense to have some stone that sometimes drops flint along with the stone itself. I would imagine a new stone that occurs near the surface of the world called chert (Chalcedony). It would be a brownish-gray rock, forming small clusters similar to coal. It has a close to 100% chance (not guaranteed) to drop one flint and very rarely two when mined. I think this would be a great addition to the game as it provides a way to obtain flint directly without breaking gravel constantly.
