I thought we already has the discussion about the 'post-apocalyptic future, living in a cave' thing, and I remember responding with something like wanting
this in my cave:
Back on topic!
Most knife fighters I've heard from or spoken to all tend to buffer what they say according to a million variables including circumstance, training, availability and individual. Almost all of them agree that reach is in many ways of paramount importance, so a longer blade is advantageous. They're also quick to point out that a long heavy blade is likely more dangerous to use, as it reduces speed and reaction.
I think your knife in the above post is almost the 'ideal', as it's long, light, fast, slightly curved to aid in the slashing cut, and pointy enough to stab with.
HOWEVER, I think it needs a sharpened clip, because the concept of a cutlass and it's 'backhand slash' with the clip seems viable to me. It should have a much larger guard, as well.
Here's a point the two of us have discussed before, too - with you and I being the perfect people for contrasting examples. What's light and fast for you (being the bull of a man you are) may likely be cumbersome and awkward for me (being in the NoAssBladesmithingSociety at 6'2" and 153lbs!).
Regarding full knuckle guards and finger grooves and skull crushers... I guess. For me, if the long blade and my 'finger of God' reach advantage didn't get me where I needed, it's likely too late!
Many pointed to Bill Bagwell's bowies as examples, Larry Harley's Battle Bowies also... these seem like good answers to me, with lots of historical as well as contemporary anecdotes to reinforce them.
I also think that Larry's design is the natural progression of Loveless's Big Bear, with the added advantages of reach and better chopping ability. It might be a personal thing (I'm sure of it, in fact), but I've never felt a sub-hilt that felt good to me... the sub-hilt portion always managed to make it uncomfortable for me. Maybe I need a custom?
I think the idea of deep hollow grinds is a great one, especially for flyweights such as myself. However, if I weighed 240lbs, I might be in preference of the additional strength that flatgrinding or convexing offers.
The '07 bayonet certainly could qualify, however at that point I'm holding the weight equivalent of a sword -- and I'll take the sword at that point, thank you. No arguing that it's certainly an effective weapon, though!
Great topic, I'd like to see this keep going!
