These hardened steel inserts are an ideal tool for cutting rock, trimming stones, shaping and chasing out channels.
They are simply pressed into either end of the double ended Scutch Hammer and pressed out sideways when blunt.
All combs have two edges per tip.
These Hammers have either a slotted end at either one or both ends. This slot is for holding a scutch comb (1" Comb, Blade, or Marble Comb) for many purposes. Cleaning up stones without the inconvenience of a chisel, or chasing grooves into walls. Double Ended allows you to have two types of Comb in one tool, and single ended provides you with a hammer face.
