"only just that an opinion from a stranger on the internet"
But if you had to hike in for a month and carry everything on your back...which knife would you bring. I bring two: a fixed HEST for camp and bush work and the HEST/F for fine cutting, urban EDC.
I think the part that you may be missing is that the HEST/F is designed by myself for my specific uses and experience. My use is that I head out for about two weeks to a month with no support or backup so everything has to work and be field expedient. It has to be affordable enough to not make me break down and cry if I lose it or give it away.
The HEST fixed is spring steel and made to be severely abused as an ax, field knife, skinner etc etc. It gets field sharpened. the HEST/F is more urban self defense product with the need to keep cutting without constant sharpening. I often augment my kit with a locally bought parang or machete. Sometimes I even carry a little Leatherman scissors for minor surgical stuff.
Nobody breaks glass with a glass breaker. But the HEST/F gripped and punched in the right spots has a very nasty trademark, just like using the pry bar in the closed hand hold on the HEST fixed. Yes you can break glass with it but you could also use the tip or handle in a pinch.
I fully appreciate that people aren't going to Somalia, Chechnya, Afghanistan or the tribal areas so they can also remove the glass breaker, they can bring a sharpener, even oil things and not get them dirty but I hope they are made more confident that I truly enjoy pushing these knives to the limit and have chosen the materials according to that use.
As more and more customers use their HESTs there will be an evolution of products to match their needs. So opinions from strangers on the internet are helpful as long as you understand that the goal is to build a light, strong, useful survival tool.
Nobody really gives a damn what your blade looks like behind enemy lines. Even less if you come back alive
