Query: Razor sharp but uncomfortable to carry

This knife does everything advertised, however the design of the thumb stud makes it very uncomfortable to carry in the front pocket. It has a fairly sharp edge, so that every time you reach into your pocket, it rubs against your hand. I've had many other knives with thumb studs (I usually carry a Benchmade 942)and have never had this problem.
