18th Century Clasp Knife from Scratch.

You will remember my first attempt at making a friction clasp knife, it turned out okay, but not the best. It was a good learning experience for me, and I said at the time I would make another one. Well I made it yesterday.
Unfortunately I had to work in good light for the video camera, this meant that when I had to heat the tab on the blade to bend it, I could not see the colour of the steel and it was not hot enough and broke off!!!
This I corrected by fitting in a pin in place of the tab, but it is not an 18th century method as far as I know. So today, I removed the pin and fitted a ring, which is an 18th century method. I think it turned out well, and I am pleased to have it and use it. It is much lighter than my present period clasp knife.

The blade I made by cutting it out of a saw blade with a cold chisel and then final filing. The handle is deer antler. I found a diagram of original 18th century blade shapes on the net, printed them out, and transfered the design I wanted onto an ice cream container lid using my awl. Then I cut the shape out.
I placed the cut-out on the saw blade and scribed the shape onto the steel with a stylus. The part I cut out I used to mark where the blade hinge pin goes, and this I transfered to the steel blade using a center punch. Only hand tools were used in the making of this knife. See what you think of it.

The design of blade I used is marked with a tick.

The pattern I made with the stylus and just to the left the circular saw blade I cut the knife blade from.

My anvil is a piece of railway iron.

The finished knife with the stop pin.


The same knife with the steel ring I made and fitted this morning in place of the pin.

  1. Nice work. The ring definitely looks more in keeping than the pin.

  3. Thank you Frontier, I like it too. Much lighter than the period clasp knife I normally carry.
