I found a razor in the local flea market and bought it because it was heavy and made in Sheffield. When I got it home and had a better look at it I realised it was only hollow ground on the "front" side, the back side is completely flat much like (I understand) a Japanese razor. It's not even all that hollow ground on the one side - maybe half hollow or even quarter hollow. I've never heard of a razor ground like this and I'm not at all sure how to hone it. Any advice would be welcome. It's a square point marked on the tang "John & Wm Wragg Sheffield Eng". Sorry no pics as my camera broke a while ago and I haven't had a chance to replace it yet.

this is most likely a razor that they uses in lab to prepare samples for slides.

+1 to what Doc says ... the reason it's only ground on one side is that, with half a bevel, it is effectively twice as sharp as a normal razor. You just hone the one side (ground side down) but I wouldn't shave with it. If you try, let us know what happened.
