We tried to get something like this going a few times, this being one:
http://www.bladeforums.com/forums/showthread.php/839104-The-Great-MKII-Kami-Challenge!/page3 It didn't materialize. The specs are out there and below are the specs on two I believe represent the Mk. II/M-43 khukuri at their best. They are light enough to be fast, but heavy enough to be great woods tools. Some war time production versions were upwards of 26+ oz., but many Mk. II, and all M-43 in my experience, tended to be at or under 24 oz. Since the linked thread, I've come to appreciate even lighter khukuri. I have a Mk. II copy at 21 oz. which, as far as I'm concerned, is ideal. I believe the legendary HI M-43 Wildmike used while living for several years in the woods was a Bura at 24 oz. I'd say 17.5" OAL, with a 12.5-13" blade, at 24 oz. would be a sweet spot for an ideal general purpose khukuri for many people. As I said, I actually prefer a few less ounces, but realize I'm in the minority

. The key is a short, but long enough for western hands, handle, and a distal taper. My period M-43 is about 1/4" at the bolster and shoulder, while my nicest Mk. II is about 3/8 " at the bolster, tapering a little to the shoulder, and thinning from there. Both handle very nicely, though I do prefer the constant distal taper. That removes the forward heavy balance many like for chopping, but adds greatly to the handling IMHO. I believe they would sell well. Good luck.

M-43 on bottom with a 1943 Pioneer Calcutta Mk. II on top. BTW, the Pioneer Mk. II's were Ok, but a little rough. They seem to have been a common WWII Mk. II.
