I have looked at many of the knives you guys have linked to, and would like to offer a humble opinion or two. Of course in the end, you'll have to decide if you like what you've bought, but personally, I immediately ruled out about half the suggestions at first glance. Why?
1. I don't much care for hollow grinds that only come halfway up the blade, especially on knives this size. I almost always prefer a full (from edge to spine) flat grind or convex grind, both with a convexed edge. Knives with a 'half hollow grind' leave you with a bunch of dead weight on the back of the blade, and a ridge line (the top of the grind) running down the blade that is not at all "aerodynamic". Also, the edge will not be aerodynamic either, since it must be about the same thickness about 1/4" up as it is at the very edge. Go out and clear some brush with such a knife, and you'll notice most of the sap and gunk will build up just behind the edge, and above the grind line. This is a sign of DRAG. I've done several before and after tests with such knives, where I reground the blade to be more aerodynamic, and the improvement in cutting performance was quite dramatic. If I wanted a very, very light for its size blade, I'd go with something from Mr Hossom, as his hollow grinds go all the way to the spine, and have better edge geometry.
2. Every time someone over at swordforum.com talks about using stainless steel for swords or knives this big, the replies are always full of a bunch of puking smilies. :barf: :barf: :barf: :barf: The experts there, and in the rags, almost always prefer some kind of simple high carbon steel with a differential heat treat. You may know that I recently broke my big Bowie. It was ATS-34 heat treated by Paul Bos, and it was 21" long. There was nothing wrong with the grinds, etc., the blade just couldn't take the abuse I put it thru. (I posted the story a week or 2 ago)
I'm not trying to knock anyone who likes or uses stainless, hollow grinds, etc. I just personally believe they're not the best choice for this particular application.
