Question of the Day: Do You Carry A Knife?

Shooting Industry News wants firearms retailers to know that knives generate Razor Sharp Sales. I reckon that cuts both ways. On one hand, knife sales add profit for dealers dealing with razor thin firearms margins. On the other hand, what do gun salesman know about knives? They have a hard enough time remembering to laser every single person that walks through the door. JK. A bit. So, do you carry a knife? If so, which one? And would you/did you buy one from a gun dealer?
