Cobblers knife ~ long blade
Leather knife ~ long blade
Although supplied quite sharp these knives are not honed to their maximum level of sharpness. It is expected that users will be keen to do in their own preferred way. Sharpening on an electric high-speed grindstone will spoil the temper of the blade and render it useless for evermore ~ water ~ or oil ~ cooled stones must be used. We suggest a fine diamond stone used with tapping fluid ~ both of which are expensive.
They have several names ~ Cobblers' ~ Clip Point ~ Leather ~ Shoe. These reflect the main user of such blades.
