Manual creasers can be drawn by hand against the leather. An example is putting the visual touch of a thin line near the outside edge of a belt. In some cases the creaser can be heated so it runs more smoothly over and deeper into the leather, and more easily crease softer leathers.
Creasers can also be used, instead of burnishing, to put an edge onto leatherwork. An example is finishing the edges of a wallet, or those on a luxury handbag.
