Some pocket knives are 100% ambi except for the pocket clip. The screw holes even allow for switching the clip, but a bend here or there in the clip body prevent it from ambi use. The knife shown below is an example - a Buck Sprint. The mounting holes are on the top edge and ambi, but the bend causes the clip to wing out when switched.

Does anyone know of a place where a custom clip can be made?
