I’m something of a knife guy. I own more than a few — and carry one. I get the reason for carrying two . . .
The one you use for everyday tasks — opening boxes, cutting food, etc. — gets dull quickly. If you’re going to use a knife for self-defense, it ought to be razor sharp So one for utility, one for emergency.
Only my clothing only provides so much real estate; a second knife is a bridge too far, EDC-wise. And while I’m a big fan of Andrew’s knife choices [click here to ID], I can’t think of one good reason to carry three knives. Can you?
