Probably durable and strong as most of what CS puts out. And do remember that it doesn't have an edge to cut with, it's for stabbing only.
First of all you should check your local legislation:
(1) Manufactures or causes to be manufactured, imports into the
state, keeps for sale, or offers or exposes for sale, or who gives,
lends, or possesses... any ballistic knife, any nunchaku, any metal
knuckles, any belt buckle knife, any leaded cane, any shuriken,
any lipstick case knife, any
cane sword, any shobi-zue, any air gauge
knife, any writing pen knife, or any instrument or weapon
of the kind commonly known as a blackjack, slungshot, billy,
sandclub, sap, or sandbag... [see below for definitions]

In short just owning it in your state is illegal, if you really live in L.A.
Sorry man, you're kind out of luck.
