I worked with a guy that would pocket a professional soldier, Dozier body guard or an Emerson police utility knife.
All have an easy thumb break or easy exit from the kydex and you barely notice them in pocket.
I tried them all out and understood why he likes them so much.
The nyala is nice but not something I would ever put in my pocket with those stock handles .
Sorry if this does not help. But for pocket carry I feel there are many better options .
FYI. He usually carried an Umnumzaan clipped with one if the above mentioned blades and a CRK 4 inch shadow on the rear of his belt .
