As to the legality of a knife length, that varies state by state. Same for concealed weapons permits. In CA you almost can't get one, in many other states, like mine, it's easy.
As to the need for one, seatbelts DO lock up, especially if you are hanging upside down, the belts taught, panicking with gas dripping on you ! I imagine the camlock types are way best, but not everyone has these.
OK, here is a special price for club cobra members. Everyone is welcome to order these items, even Turk
My website is:
www.omegamanenterprises.com
We do not take phone orders, only on line secure Credit Card or mailed in US postal money orders, either way, use the on line order form to get your total, and a final form to mail in if you go that way.
Choose the ultra light shipping option on the order form. These prices are good only for cobra club members and those who mention it in the special instructions box in the order form. This price is at my cost, but the lowest shipping charge I can offer with my system, is the $9.00 U.L. option, so The end profit will be about $2.00 each. You may order up to 10 knives at that one shipping price
Be patient, if I get deluged, my distributor will have to backorder them !
