So I've been contemplating making my own knuckle Dusters. They are illegal to purchase or import in Australia. I don think its illegal to construct your own as long as you dont sell them.

So I was thinking of charging $150. What do you guys pay in the states? And are there many different types? Sterling silver, brass, gold etc etc. I just plan to buy sheets of 1/4 steel and drill out my own. Then Ive read that grade 2 steel wool is used to make them smooth. Its a pretty simple process, im just wondering if its going to be expensive and time consuming to produce. Has anyone tried this before?

I was wondering about the method to melt down leftover steel and pour it into a template, Although I dont think that it would turn out as well as a drill job. Any thoughts?
