Funny, that no one mentioned cliff stamps comparison that he did back in EARLY 2000. I guess most of you do not remember or were not around. Anyway, he came to the same conclussion I did. In order for the khukuri to be more effective than the BM it has to be much bigger and have much more weight up front.
The largest 15 inch khukuri is the 15 AK. Yet, my SHBM outchopped it every time. When I got the 22 inch AK, it chopped better, but was to hard to control at nearly 5 lbs. So when I asked HI to make me an 18 inch AK, he had the Kami's do it for me and it proved to be perfect. It chopped better than my SHBM by a slight margin. After an hour though the SHBM would come right back, because it was lighter, much lighter. Also held an edge better.
About the only person on the boards at the time that had as much chopping experience as me when using these two knives was cliff. I chopped about 7-8 chords of wood over 5 years using nothing but, my SHBM, 18 inch AK, 15 inch AK and an assortment of other knives that broke during these sessions. I lost most of my ontarios during this time, except for the marine raider. I used a GH Khukuri for a month and it fell apart.
Also, I could never get the Khukuri throwing down, so I used my SHBM to throw at the logs in between chopping sessions. I broke many other knives doing this.
I would love to have a Busse Khuk, but not because it is more efficient than the BM, because it is not, but because that would be the coolest busse ever.
