I am going through some old threads and discovering mentions, references, ideas, etc. with regards to coffin handles, vest Bowies and such... Makes me feel a bit lame, being the new guy and barging in with all of this stuff.
Ah well, if it helps move the idea along, I guess I'm good with that.
Continuing with the topic with regards to features:
Ricasso length, like with anything, is largely a matter of personal taste. I am not too keen on an exaggerated or long ricasso, I think it takes away from the aesthetic and leaves a lot of unusable steel. I also do not like when there are abrupt or squared off heels.
I think the best example of something that represents what I do not like in this regard is the Spyderco Respect Bowie.
I think the ricasso should certainly be proportionate to the size of the guard, yet still have some subtlety, and that the heel, (if any) should be far more graceful.
In regards to some other features, if Blackwood is the used handle material, then a small spacer, paired with two rows of small pins, in either nickel silver or stainless, would look particularly striking.
