So--you see the Khaki sets, etc. from WWII. Were safety razors issued to the troops in Viet Nam in the 60's? Or had they change to cartridges by then? Trying to figure out if my old man might have one laying around in his stuff. I could just ask, but that would be the mature way to handle it. I haven't looked through that box for 25 years, and 25 years ago I probably just would have called it junk. Thanks.
