I've used both coil and leaf springs for making knives and they work great. I have absolutely no idea why I didn't think of using that material for a razor: thanks for the nudge.
You are very welcome. Cracks are a risk, but this particular piece was from a “mall crawler” truck (all show and only a few easy miles). The springs were like new. I have seen cracks in old leaf springs though.

Personally I think old automotive springs make better razors than they do knives.
