A scutch comb is an attachment that, when attached to a scutch chisel or hammer, becomes its cutting edge.
It is detachable and can be taken out of the scutching tool and flipped over to allow use of the second cutting edge.
A scutch comb is used specifically to make marks across a surface. This is useful for creating texture on a sculpture or for providing grooves on a wall to help plaster stick to it.
What are the different parts of a scutch comb?
Each scutch comb has two cutting edges (rows of teeth), which must be sharp in order to cut through material effectively.
Scutch combs also have a ridge, which stops them from being inserted too far into the scutching tool. When inserted, the ridge rests on the lip of the scutch comb holder.
