Serious chisel for serious mortises.  Socketed construction with long bevel for chip breaking. 
Turned beach handle.
Traditionally forged from reclaimed wrought iron with 1095 forge welded business end.
6-7" long business end for deep mortises.  Slightly back tapered to clear walls of mortise.
 
Please indicate desireed with: This is a good size for 1/2", 5/8" and 3/4" mortises.  I will make them larger upon request, but 7/8"+ mortises are usually bored for stock removal and cleaned up with a framing chisel.
