Hi Lars. The double pippen punch was used for making a slit with a round hole at each end for locking straps on luggage and gun cases.After bucking the strap,the slit would be pulled over a d-ring( the bars of which would poke out of the strap through the round holes) that you could put a padlock on.I've seen this on leg o' mutton cases.I've got two by Joseph Dixon.They are 1" and 1 1/4" between the holes. I don't think they're made anymore,but you could check with Dixon. Cheers(sorry, SKOL), Sean.
