Here’s my Kimber custom shop CDP II which is one of my primary concealed carry pistols, and one of my Benchmade Hidden Canyon Hunter fixed blade knives.
I have two of them, one of the old style with a slightly shorter but thicker blade and this newer one with a slightly thinner and longer blade. Both versions are great knives that are ideally sized for pocket carry.
Both of them have Armatus Carry kydex sheaths with an Ulti Clip. The Benchmade sheaths went from not great to downright bad in terms of quality (pressed leather), they just were not practical for pocket carry, and were not all that great for belt carry.
The Armatus Carry sheath and Ulti Clip lets you carry the knife in a front pocket where you can draw it one handed and ready to go. You can also clip it at the back of the pocket and leave the handle exposed for easier access or clip it farther forward so the handle is completely hidden in the pocket of concealment is important.
