It was designed to be the end all woods knife.
The story behind the Machax, is a creative one. Ethan sent some kukri's to Vietnam with some friends, the friends came back, and the kuks didn't. They were found lacking by all parties. So it, started. The first BKT creation. It was a combo of the Pack Machete/Survival Machete and Kukri knife. The angle was set to facilitate a snap cut, which, the BK4 does so well, and really bites. With a flick of the wrist, it will take green veg like it wasn't there. Then, came the effective recurve, for use as a draw knife, with the wider head, you have a place to get a good, solid grip.
As for other knife duties, you have a sweeping, long edge, that works well in just about every grip, except reverse. As a combat tool, well, use your imagination. With the wider flat of the front, you can dig, and its small enough to bore holes in wood, and the spine thickness lets it baton with ease.
Ethan's first creation, and one of the finest general use woods tools out there.
