Overly tall, narrow, slab-sided handles that substitute aggressive jimping and finger grooves for a more hand-filling, 360-degree grippable handle shape. Manix, 0350, Shallot, Tenacious... knives seem to be the only product made that eschew an ergonomic grip for aggressive edges that are fatiguing to use over time, rather than a suitable hand-filling grip that allows greater contact area and lower overall pressure for the same grip strength. Yes, I know, thin is in for pocket carry, but an extra 1/8" of thickness, rounded corners and a swell in the middle of the handle aren't going to make something uncarryable.
