Crescent Wiss® Heavy-Duty Titanium Coated Tradesman Shears 4" Blade. Feature premium-grade steel blades that extend through the handles for twice the strength and ten times the cutting power of standard shears. Their titanium blade coating is three times harder than steel for extra durability and longer edge life. A serrated bottom blade grips material for better control and cleaner cuts, while optimized handle contact points and an index finger "control channel" improve cutting power and increase stability.
