This question was posted by JBCohen in another thread so it was moved to this thread. Can anyone tell me about when did the straight razor first appear in its current form? When was the carbon steel first introduced? Can anyone explain the different types of grinds available?
BJ, Here is some good information for you to read, Enjoy! http://www.en.nassrasur.com/razorcentral/index.html
Here is more information about the history of straight edged razors. The second part talks about more modern razors.
As an addendum to this post, if you need some information about when a particular brand was made, check out this site.
I ended up the sole bidder on this replica of a razor from 1500 B.C. The original sits in a museum somewhere...
