heh, an extra hole in the leather, i mean. ;)
it turns out it was easy, here's how:
1. using a sharp tipped knife, press firmly on both sides of the belt in a star pattern ( * ), do feel free to wiggle the blade to try to get it to really penetrate, especially when coming from the reverse side.
2. using a narrow tool of some kind, perhaps a very thin screwdriver, press it against the nascent hole and apply great pressure in order to push it through.
3. once the narrow tool has penetrated the hole then check the size of your belt buckle and try to choose a philips head screwdriver of similar thickness. with this tool you should press firmly from one side and twist the screwdriver to actually shred out some of the leather. when you can see the tip on the other side you should then do the same procedure on the reverse face of the leather.
this should result in a fairly nice and clean hole in your leather belt.
to hold the belt firmly while doing all this wiggling and twisting you should be sitting, place 1 foot on the long buckle end of the belt, grasp the end with the holes, and use the opposite hand to drive the tool of your current step. this will allow for maximum tension in the leather and maximum force from your tool.
it's so nice not to have to push my gut out to keep my pants from falling down!
