As seen in the previous picture this is a Swiss made chisel. I call this a new chisel, I've had it close to fifty years, as opposed to most of the chisels I use that are from the 19th century. 18th century chisels are hard to come by, but I do have four mortise chisels from the 18th century that I treasure. Every time I use them I think of the hands that have previously held them and the thousands of mortises they've cut ! Refer back to picture # 1 to see the brickwork in place.
