I just got lugnut and blackarachnia and i really like lugnut but the mace won't open by "slamming the base" as it says on the package, i thought it would easily open up so i push it, then i gently slammed it, but nothing. the hinge at the bottom just comes apart. i'm not sure if it's notorious for this or the system in the accesorry is jammed. i appreciate the help and i'm sorry if this was mentioned already. thanks!
