I'm not a huge fan of the design.
I like a lighter knife- Admittedly, I've only handled the TOPS version, but it felt like a cinder block in my hand and on my hip. If I need to pack something that heavy I'd rather have a good camp axe or khukuri, coupled with my Swiss Army Knife.
I have no use for a sawback. I don't do stealth missions, If I need to cut something I'm gonna hack it quickly with the primary edge. If I'm doing trap triggers and such, I'd rather use my small sharp folder to cut the notches.
The Drawknife aspect doesn't impress me...If I need a drawknife I can do splendidly well with a Machete, a Leuku, or a Khuk. between the drawknife section and the chopping section, there's just too little blade there for me to do either job well.
I'm not gonna lash my primary knife to a stick to spear fish and stuff. There's still too much risk of losing it in a river or lake. I'd rather use the edge to carve a spearpoint and just fireharden it.
I'm not gonna throw my primary knife. I threw and lost enough knives in my youth to have learned better. I usually have a gun or other weapon with me. If not, a piece of Birch or Willow is a helluva lot more expendable to throw.
Khuks, Goloks,machetes, etc. are much nicer for clearing brush, and can do it with less physical exertion.
I just have no use for an arrow straightener. Maybe a diehard archer does, but I'm not...
Overall, I prefer tried and true knife designs that have proven themselves historically. The classical Golok, Leuku,machete, Khukuri, Hatchet, Tomahawk, Gaucho, etc. have proven themselves for a long time in history. They wouldn't be around today if they didn't work well.
Admittedly, I've never owned one, but...I didn't have to look at a Yugo much to figure out I had no interest in those either.
I'm not saying it's a bad design, Tom Brown clearly knows his stuff, and it works extremely well for him and his students. But...I'm not Tom Brown...I'm just small town whitetrash that happens to find time to stumble through the woods now and then.
Not a bad design- just a bad design for me.
Edited to add: Just for perspective of what I DO carry, it's usually my BK&T #5 Magnum Camp and a SAK Adventurer. They suit me well, and both are VERY tried and proven for me.
