Tough, tough, tough!
These are ALL terrific knives and their makers and owners should be rightly proud.
But there has to be one winner. Given that these knives are the best of the best, but there has to be some way to distinguish, I am forced to rely on personal preferences and peccadilloes. With that in mind . . .
1) Nothing not to like on Karl's Bowie. I own one of his take-down Bowies myself and they are fine pieces. The ONLY very minor nit for me is that I would have preferred a slightly longer (especially on the blade side) and thinner/more tapered guard. Again, extremely minor and just personal preference.
2) Yeah, this knife (and # 1 for that matter) may look to be more "fighter" than "Bowie." So the only thing against this one is that (to me) this does not scream "Bowie." But this forum gave up a long, long, time ago trying to define that distinction for this contest, and this knife clearly fit into the rules for this contest. Otherwise, having seen and held it in person (and having tried and failed to buy it - LOL!), there is nothing about this knife that I would change.
3) Some really cool historical materials in this one. Must be really neat to own and be able to share the stories with friends and acquaintances when they see it. But personally, I do not care for the way the Damascus turned out. So when you take away the mythology of the materials . . . it did not make it for me.
4) Absolutely gorgeous piece! Look at that Damascus; look at that stag! The level of effort and difficulty on this one had to very high. Maybe even this one should win on merits. I am just not personally a fan of this kind of large and elaborate guard. It is just as simple as that for me. But that is a personal quirk, and if I had to guess, I am thinking this one might do well.
5) Now THAT is a Bowie! If I am in a fight, I am probably choosing this one. And I think this is the kind of piece that usually seems to win this award. But aesthetically, the handle shape seems odd to me (maybe I would understand better if I held it), and the guard seems a little clunky to me and does not flow. Again, extremely minor matters of personal opinion.
So in the end, it came down to #1 and #2, and I vote for #2.
