Thanks, guys. If I get one, I think it'll be the SP50. I thing the Kabar (if it were sharpened on the back curve) would be a better shape, but it's not & it's $150. Plus, I have more use for an axe with a pocketknife than a large blade. Still like the large blades sometimes, though.
Something I was thinking about: I truly think that the tradition of having a large blade for dueling purposes that can also be used as a general-purpose blade is a good one. Think about it: The small blade makes it hard to not get nailed in some way (since it's can be much harder to intercept), but the large blade is something that can be parried & such- if the fight is MEANT to be non-fatal, the bigger knife is oddly the better choice. If it IS meant to be to the death, it would certainly still be useful, but it makes the other option more possible.
I remember hearing that the Gaucho would duel in a way that wouldn't normally be a smart idea in a serious fight (flourishes, showing bravery by sticking their stomachs out, etc...). This is more possible with a long blade than a small one, since it's not quite so obvious what's going on in a fight with such small & fast weapons.
What do you guys think of this? I've got to assume there are people on here that know quite a bit about this subject, even though it's not currently "in vogue" in America.
