How it works

A belt is a strap and a buckle. The strap carries the holes, the edge stitching and the tip; the buckle is a frame with a bar across it and a prong that swings from the bar into a hole.

Read the full guide

Doing up a belt

Feed the tip through the buckle's frame, push the prong through the hole that fits, and tuck the spare length under the keeper, the small loop beside the buckle, so it lies flat.

Parts of a belt buckle

The frame is the outer rim. The bar runs across it; the strap folds round the bar, and the prong, also called the tongue, hinges on it and rests on the far side of the frame.

  • The stitching runs along both edges of the strap: it strengthens the leather and gives the edges a finished look.
