This is a second version with slightly changed dimensions from the first batch

I left as much of the pattern the bronze came with on them as I could and still sand them flat

The clip is designed to go into a uniform pen pocket

It is 3/16 inch thick brass and the same size as a credit card

Mars XL brass knuckes The holes areI'm calling this the Mars XL because, quite frankly, I can't think of another name and it's a modified Mars. These are 1 2 inch thick brass. They are similar to the Mars, but have the obvious extension into the palm to help keep the point straight. Oh, the point is also a little bigger than the Mars.
