In some parts of the USA, that BFK (fixed blade) is illegal to carry if the blade length exceeds X. Std Ka-bars usually exceed the blade length limit in areas with such laws. Knife laws are sorta like gun laws, in that they vary by state, county or city. You can be JRA, cross an invisible boundary and suddenly your weapon is illegal to carry either open or concealed - so do your due diligence and avoid expensive legal mistakes.
