Hold on a sec, someone said the BK-9 can't chop well? Rather than call that person an idiot or crazy or anything, I'll just say that I have a different opinion!
My choppers:
My BK-7 is VERY noticeably behind the other 3 in chopping performance, but it is amazing how close the other 3 are. The BK-9 didn't quite match the HI Ganga Ram, but it wasn't all that far behind.
Here is my thread on the chopping tests:

2m30s for the KA-BAR Kukri Machete, 2m45s for the BK-9 and the Ganga Ram was able to chop through the same wood in about 2min. The Ganga Ram does weigh about 26oz so you have to expect it to be a better chopper. If I improved my technique so that the BK-9 didn't jam in the wood as much I could have chopped noticeably quicker with it.
