Key Features & Benefits
- Compound-leverage action — two-pivot design multiplies hand pressure for clean, low-effort cuts through gauge steel that would crush a single-pivot shear.
- Forged and heat-treated blades — ground cutting edges hold their profile through thousands of cuts; resist chipping when closing on harder than rated stock.
- Yellow handle colour coding — follows the industry convention for straight cut, so the right snip is instantly recognisable on a cluttered jobsite or van floor.
- 248mm (9-3/4″) overall length — the standard aviation footprint: long enough to deliver leverage for thicker stock, compact enough for one-handed overhead work.
- Spring-loaded return — the blades re-open automatically after each cut, reducing hand fatigue during repetitive trim and duct work.
- Latched handles — safety latch holds the blades closed when stowed; releases instantly with a thumb flick when you pick the tool up.
When to Use This Snip
Colour-coded aviation snips are built around cut direction, not dominant hand. Straight Cut snips produce their cleanest cuts when the waste side of the metal curls to the direction the snip was designed for. Match the colour to the line you are following, not the hand holding the tool — many tradespeople carry both a red (left) and green (right) snip in the same pouch for this reason.
