WOW, just WOW.
I don't know, but I suspect that hidden somewhere at my Nan's place is a straight razor that used to belong to my late Pop, IF it's still there I'm dreading the condition that it's likely to be in, he passed away in 1983 and if memory serves had abandoned straight razor shaving in favour of cartridges (who knows why?) for some time before that.
Seeing a transformation like that really gives me hope that if it turns up it can be restored to something resembling it's former glory.
I really hope it does turn up, even if it's not able to be restored to a point where it can be shaved with, I'd really like to restore it as an heirloom and a reminder of my Pop, he really was a great guy, one of nature's true gentlemen.
