They were a very limited run of about thirty. Made by an Australian coin cutter (Cocks Customs).
Sal had obtained some coins cut in the Spyderco bug design from him. Sal then gave him the ok to use the Spyderco bugs design in the limited run which was made in 3 (I think) different patterns of Damasteel.
That was a few years back and I don’t think any more have been made.
Well; by that coin cutter at least.
