If you have a micrometer and want a laugh , you know those orange and white BIC disposable razors. I took one apart, and I couldn't believe that they would sell a razor with a blade that thin.
Thank you for all the information. That's some really cool stuff. Information like that is hard to find. Much appreciated.
In the B&B link in my first post (#8) a British New Gillette blade was actually measured to be thicker (.0067). Not that I necessarily trust the accuracy of those measurements, but it certainly does seem the old standard was. 006 and the new 004 with the latter beginning its dominance around 1937. And contrary to claims regarding the Personna med prep in that B&B thread it is also carries the. 004 spec.
Holy COW, Batman! My thoughts are that this gentleman is: A, an engineer, and B, employed by the federal government. Apologies to any Federal Engineer types. I tease.
I had to tap out on that one. I followed that link to what must be the longest everlasting post I've ever seen.
