Ah the RAT DPx H•E•S•T. I am glad it generates such interest and controversy.
I guess I would have to separate the comments from theorists versus from users. Its quite easy to make up critiques but the HEST is a real world knife, its not a tactical poser, or country boy antler stick. Its a tough razor sharp, well thought out EDC at a great price. Let's discuss what makes this knife worth looking at:
- Its a US made, massively thick, legal-carry, big-handled bruiser that comes with a lifetime no questions asked warranty. That alone makes it worth buying. There just aren't that many hard knives in that category and for under $100 bucks.
- the prybar, love it or hate it, it adds a massively useful tip saving element to the knife. If things get slippery you will also understand the ergonomic reason its there (along with the four finger hold of the skeletonized version) The extra purchase of the prybar also makes it sit in your hand like it lives there and provides a perfect thumb spot. I agree that some people look at the pry bar and scratch their head but then again I look at some of the knives that claim utility features and I scratch my head.
- The "beer opener" its yet another pry tool and that magic spot that your thumb rests on for carefull work. Its called a beer opener for a laugh. Real men drink hard liquor anyways

) The mounting points and mirror choil and beer opener are functional lashing points as well.
- Hollow handle, wire cutter choil, open grip, bottle opener, lashing points are all there because they work and actually add to the ergonomics and function of the knife.
- the designer. What can I say? After two decades, numerous remote expeditions, 36 wars, 120+ countries I wanted a knife that would work in the real world. Famous knives from the Bowie to the Fairbairn Sykes have always been a the result of the requests of of real world users not not "knife makers". It is a three way marriage, the designer, the maker and the user. And it should be small select group that loves the knife. And the designer should actually listen to the users to constantly improve the product. That's why I like going to SHOT, reading comments and talking to users.
As for comments on the RAT folks and their products. You are right you won't see RAT's hanging in Wal-Marts and don't hold your breath for the new RAT Klingon War Axe but if you make it out to the boonies, Iraq or Afghanistan you will see their knives in use. And once again, you won't find a company that stands behind their products like they do.
For those who don't know me. Here is some stuff:
