The Irwin Vise-Grip 2073111 aviation snip cuts straight ahead and curves to the LEFT, following the universal red-handle convention for left-cutting tinner snips. Hot drop-forged blades hold an edge through repeated cuts in cold-rolled sheet steel, aluminum, vinyl siding, and screen. The compound-leverage handle multiplies hand force so a full thickness cut takes less squeeze, and the serrated lower blade grips the workpiece to prevent the metal from slipping ahead of the cut.

• Cuts straight and to the LEFT (red handle convention)
• Hot drop-forged blades for strength and edge retention
• Serrated lower blade for cleaner, slip-free cuts
• Safety latch with one-handed release - lock the snips closed for safe pocket carry
• ProTouch cushion grip handles for comfort and control
• 10" overall length, compound-leverage design

Tip: Use left-cut snips when the WASTE side of the cut is on your RIGHT - you keep good metal in your left hand and the offcut curls out of the way. For HVAC and sheet-metal work most installers carry all three colors (red/left, green/right, yellow/straight) since the right tool depends on which side of the line you are saving.
