This is an excellent idea. Thank you. I did some research on it and that stuff is extremely strong. I don't think that you need a metal liner or cheesecloth. How did you make and attach the wedge? From what I can tell, adhesives don't work on it well at all, but you can "weld" it with a heat gun.

This would be really cool with a blade forged from a recycled car spring. Imagine having a functional, good looking and unique razor that was made completely from junk. It would just be cool to have something worth a few hundred dollars that cost $0 in materials and that other people had thrown out. One man's junk and another man's treasure, so to speak. I think that I just found the next razor project to add to my collection.
