“Guillochage” is the decorative pattern engraved into the back of the knife. They are all made by hand with a file. I choose it according to the style of the knive it decorates.
On my folding knives, the guilloche is mainly on the plates. Sometimes the spacer is decorated too, especially when it is metal.
Fixed knives offer other possibilites for the guilloche.
Here are some of my latest creations.
