I currently carry a CRKT m21 special forces 4 inch folder weak side. I am looking for a knife around 4 inches that WONT cut my car seats. The CRKT prongs which make it a good knife will cut your seats. http://www.crkt.com/M21-Special-Forces-Double-Flipper-AutoLAWKS-Combo-Edge An assisted opening knife would be nice. I like the Kershaw series but they dont have anything to keep your hand from sliping onto the blade. Would also like it to be well balanced. I want to carry this strong side rear pocket as a back up to my weak side front pocket for unarmed zones. I carry the 6 inch Cold steel folding kukuri in the woods when hiking. But this would not be well accepted in regular public areas.
