Previously existed in 1.19.2 with the bamboo backport, but due to it being removed in 1.20, it no longer exists.

2 Blocks of Bamboo (Not planks) make 8 sticks
8 Blocks of Bamboo make 2 Bamboo Chests

NOTE: These are halved from the usual 16 and 4 of said chests/sticks due to bamboo giving half as many planks per block
