How to take a prong off a buckle

Most belt buckles come with a metal prong. While some antique buckles may have casein prongs, which are impossible to remove without breaking the piece, the prongs on most modern buckles are easy to remove. In my shops I do it as a standard service, but if you have bought one WITH a prong and now you have changed your mind, don't worry. It is easy to fix.

These yellow buckles originally had a metal prong
but the customer requested to have them removed.

You can do it in two different ways. Sometimes one way is better than the other.
