HD comfort are manufactured to all relevant DIN standards & are constantly inspected for hardness, torque & bend-load. Shatterproof cellulose acetate handles. Injection moulded onto the blades - giving total handle to blade security with no turning or slipping. Combination of bevelled square shape & wide surface area results in fatigue free high turning power.
