The ramp is ONLY useful with the thumb beneath (as originally intended, clear from the jimping and older sale images) for piercing, etc. When BRKT realized that they designed it badly, they claimed that the underside was for striking a firesteel - except that the edges are soft and somewhat rounded there so it only works with a great deal of force, i.e. a VERY poor choice of striker unless modified by the user - and that proper thumb-placement was
above the ramp, which
decreases the amount of force one can place on the spine for notching, etc. (as the new sales-pitch suggests)! BRKT soon began offering the Bravo 1 "rampless" and now has their "field" model with jimping like Survive! and ESEE knives instead of the useless & uncomfortable ramp, as users were grinding them off themselves. Even in hammer-grip, the thumb-ramp is obnoxious as it rasps the junction between thumb and index finger in use. Some users are just complacent enough to accept the ramp as it is, as the knife can still be used despite the obvious mistake.
I like the comparison to the MUCH cheaper Becker scales, also known for being slick

and ESEE's scales, known for being uncomfortable because of their shape and short length. But, amazingly, these are not the only handle designs out there! Take a look at the Survive! Knives GSO-4.1 or the Swamp Rat HRLM reviewed
HERE. One could also look at ResC (bussekin) or other rubberized handles, but those more easily suffer damage from abrasion. I personally believe that handle comfort and security is second ONLY to structural integrity of the knife (which includes edge stability). A knife needs to cut and should be safe & comfortable in the use for which it was designed.
