S3 Premium Shears are hand-polished, high-performance Swedish Steel shears that utilize innovative steel treatments which positively alter the steel ensuring a longer blade life. Blades are forged to the optimal hardness, ensuring they are not too hard, which could result in cracks, and not too soft where the sharp edge can collapse. We are proud to offer a high quality shear that incorporates Swedish Steel technology and is priced to fit all budgets. Hand Polished Swedish Steel Convex Edge Adjustable Tension Knob
