Hand forged

This is a set of spurs I did a while back, just to see if I could. They are forged from 4140 steel.
The biggest mystery to me has always been; how did the old masters forge the bottle opener into the shank?
Here is how I did it.
I  forged every thing to shape, leaving 1/2 inch between the band and the 90 degree turn on the shank, made a cut with a hack saw about 3/16th's back, heated, and drove a chisel in the split rolling it under for the bottle opener look. I hope I did Mr. Bianchi proud.
The concho/coin screws on to make it easy to get leathers on and off.
These are for sale. 425.00$ plus shipping.
