ok we all here at cpf know what a excellent product mr gransee and his team produces like the arc aaa. but the other day i split my fingernail while dirtbiking, went back to the campsite to file the dude down a bit but could not find anything usefull until i realized that the knurling on the arc makes for a great finger nail file. now if i can just get the light to change the flat tire i received when i hit that stump. oh i forgot, it can do that to.
