Honestly, I think the wooden chisel should be used for something we actually need. Since there are already multiple ways to get a slab, I don’t see the point in wasting an open chisel spot on a slab.
Make the wooden chisel a new slope chisel. A slope that spans two block lengths. The current 45 degree slope I feel is too steep, so a slope that would take 2 blocks in length to reach 1 block in height… if that makes any sense.
