Those knives are the ones that people would classify as a defensive knife, if you're in other countries like maybe Europe or Australia, there's no CCW's where you are, if you defend yourself in the public with your gun on you, even if you live, you'll be heavy charged and/or imprisoned.ntnfancy also thinks his knives are weapons... IMO I'd use a gun, not a knife...
When I go out, I don't have a weight limit, but the heaviest knife I own is a byrd cara cara which is 5.6ounces, I have no problem with it in my pocket or on my waistband, in gym shorts, I would carry it IWB. At home my weight limit atm is 4ounces because I wear short shorts with the waist band pretty loose and heavy knives pull my pants down(I carry IWB).
