The G is for Gem + safety bar = G-Bar. Plus, K-Bar was already taken.
It does look like it should be wearing a big spiked heel shoe."One footed hoe" is pretty catchy.
I had an Ever-Ready razor at one time and if I remember correctly, it was a blank circle.Question for you G-bar owners: Ever-Ready also made a version of that razor. Did it have a letter on the handle too? Presumably not G, I'd suppose.
