So I'm hitting the big 4-0 in another month and my wife was asking for BD present ideas...naturally I thought about a razor. I have only been straight shaving for a couple of weeks and am using 2-4/8 that I bought shave ready from a member here. So here'rs my criteria and any advice or if someone knows of one or a couple for sale please link it in:

Size-I'm thinking 6/8 simply because that is what everyone says makes a good shaver but am open to ideas
Style--I'm totally lost about grounds so any advice would be appreciated. I generally HATE collecting things that I don't use so it HAS to be one of the best shavers as I intend to use it daily.
Scales--love the look of ram's horn or stag antlers
quality--again this will be used daily and I want an heirloom quality piece I can hand down to my son, so it must be of highest quality/craftsmenship.
Age--muuuch prefer something old with history but might also consider something new. I'd prefer something with some patina and no blade etchings but again this is debatable.

So just curious if anything jumps right out that might fit my needs?
