Part of the putty knife

Putty knives generally consist of blades and handles. Blade materials are mainly carbon steel (45#, 50#), 65MN and stainless steel. Blade surface treatment is generally divided into ordinary polishing (grinding steel strip when it leaves the factory) and mirror polishing (a metal steel strip surface treatment with the same mirror effect). According to the user's habits and uses, handles can be divided into wooden handles, plastic handles (plastic handles are beautiful in appearance and comfortable to feel), iron handles and all-plastic putty knives.
