Here is a simple little penny knife that I put together to test some blister steel I made. Not sure whether blister steel would have been used for an inexpensive knife, or if they would have refined it to shear steel first, but figured it would be an interesting project.
Rosewood handle is about 4.25" long and tapers down to .700 at the bolster. I loosely patterned it after some of the originals I have seen online. There were a few things I would do different, but overall it seems to have come out OK.
