The full-jaw apex tear (over-closing the snips)
Closing aviation snips completely forces the bypass tips to pinch and tear the sheet rather than shearing it cleanly. Use short, rhythmic 3/4-strokes. Re-open the jaws right before the blades hit their absolute crossing apex. This keeps the tool centered.
Stop if
- Stop snapping the jaws completely shut. Shorten your stroke to three-quarter bites so the tips don't pinch and rip jagged fish-tails into our collar layout.
Watch out
- Do not force the tool through the problem or substitute the wrong tool just to keep moving.
Check
- Confirm which snips or shears match the cut direction and metal thickness.
- Keep the good side of the sheet flat and let the scrap curl away.
- Use short controlled strokes instead of fighting the tool.
- Stop if the blade drifts, binds, or starts tearing the sheet.
- Correct the tool setup before the edge turns into rework.
