Our The 7” Muscle Shear gets its name in part from the powerful cutting action afforded by its design. Featuring stainless steel blades and a bent construction, one blade is serrated for firm grips and powerful cuts on and through tough materials like aluminum, canvas, carpet, leather linoleum, rubber, and more. To compliment the robust set of blades on the Muscle Shear, the red plastic handles are large and designed with comfort in mind. This way, you can worry less about hand fatigue and more about making that perfect cut through whatever material you find yourself with.
