Stonemason's chisel (5)

Chisel used by stonemason.  It has a small blade that tapers unevenly  toward a squared shaft with chamferred corners.  The end of the chisel is rounded to withstand impact when struck with a mallet.  Mason's name is on the side.    Stone was worked using a range of tools including saws and chisels.  Stone mason's tools have changed very little over the centuries.  Finer shaping and detail was worked by striking chisels like this with a large wooden mallet.
