This is very interesting... I'm making a feather and due to the rules of most tournaments not allowing high speed spinners and too many flippers everywhere I wanted to do something else. A crusher is oen of my preferred options. However I'm not convinced they have a place anymore due to hardox.... so I have a question, what tip pressure would be required to pierce hardox of maybe 3mm to 5mm,, and what material would your tip have to be to accomplish this?? Anyone know? Or done it? Lol
