The idea behind the barb wire - good. The execution of the idea - not so good. (literally almost NO thought to the process behind it you can somehow spool out this razor wire without tools yet you cannot unspool it without tools how? what did I secure it with? did I screw in screws or nail in nails with my mind? I don't understand it) They need to make it so you need the stupidly rare tools to put these things up that would stop alot of these people who find some and just use it to block doorways as they would need to have those tools first. Or someone will explain how they justified this put this razor wire up without tools then NEEDING tools to take it down it's kinda baffling
