This is a traditional shoe maker's clicker knife, made by Barnsley of Sheffield. It's great for cutting curves and pattern pieces accurately as it's such a well balanced and controllable little knife.
The comfortable wooden handle has metal jaws which open and close by turning the central ferrule, in order to fit a blade.
Two blade types are available for this knife (Not included with this knife handle, so please choose your blades separately)
These blades can be sharpened many times on a strop or fine stone, or simply replaced if you prefer!
