Can I open this topic back up a bit?
I was looking around at another pair of boots from the same source, and got a little more info:
Beckett Simonon say they employ a McKay machine to perform the Blake stitching. They go on to insist that because of this, the shoes are easy to resole.
McKay bought the Blake patent during, what, the (U.S.) Civil war?
Anybody familiar with the McKay machine? Can it possibly produce the Blake Rapid stitch? Are Blake (McKay) stitched shoes easy for a reasonably well-stocked and well-trained cobbler to resole? Or must they be sent to a manufacturer?
