So I got a WW2-era Tech issue package from Ebay. Included was a package of blades, still in the celluloid! Here's a picture of the one I unwrapped in order to time-date the razor:

Has anyone ever tried these blades? How aggressive are they? Does anyone want to try one? I don't see the point of hoarding blades that aren't in production anymore. I'm keeping the one I unwrapped, so I have four left.

I used one of these a while back and would compare it to an Enders se blade a great shave the first shave but tug and pull if used more than once.

Hmm, I'll give one a go this week. Should anyone want one of these, let me know.
