The size of a scutch chisel refers to the length of the scutch comb holder (the groove that the scutch comb/ drove is inserted into).
Scutch chisels (the length of the scutch comb holder) are available in sizes between 13 and 50mm (½ – 2″).
The overall length of the scutch chisel is always 200mm (8″). The diameter of the scutch chisel is not always mentioned when you purchase the tool and different brands vary in diameter.
The length of the scutch comb must be the same as the scutch chisel’s holder otherwise it will not fit correctly. The more precise the work on bricks or sculptures the smaller the scutch chisel needs to be. This is because the bigger the scutch chisel; the more material will be removed.
