I had a Hest 2.0 as one of my first heavy-duty knives. I didn't like (and still don't) the rotating lock thingie, and the blade was so short and so thick that I felt it was just not my cup of tea. It's a good pry-bar. The lock was a bit sticky although seemed to get better after a tiny bit of exercise. Do keep in mind, however, that I love the Spyderco Techno, with its short, thick CTS-XHP blade a lot and have owned four ANIB. I've never carried a Techno either; I just go through a lot of knives and these are all pass-throughs. They make great trading material, because the Techno is a Taiwan-made knife and is put together like a champ. Some of Spydercos best models are made in Taiwan...as is the TUFF
AND the Gayle Bradley, another favorite of mine.
The HEST was REALLY clunky; the Techno is not...IMO.
I have a NIB TUFF in the safe. It's beautiful, but it's a two-hand opener, unless you're really strong. The detent is unreal. I admire the quality of the build, and it's a CPM-3V blade-steel which is outstanding. I'm saving this one for the Zombie-attack. I could take down a house with that thing. The Tuff is about the size of two or three HESTs...all rolled into one, but the quality is there. The TUFF has a Chris Reeve Integral lock and an oversized pivot; a wonderful folder.
I love the TUFF; have no use for the HEST. Keep in mind that I've never used either one, and am just speaking about what I consider to be the quality of the build, the basic design and usefulness of the folder.
Don't flame me, folks. This stuff is ALL opinions, and worth what you pay for it.
