What do I do when the full-jaw apex tear (over-closing the snips)?

What to check first

• 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.

Likely recovery path

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.

Use this as field logic. Final dimensions, approved materials, tool settings, safety rules, and code-required details still come from the foreman, project specs, manufacturer instructions, employer policy, and AHJ.

Ask Foreman

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.

Do not do this

Do not force the tool through the problem or substitute the wrong tool just to keep moving.

Why it matters

Bad tool execution damages material, slows the journeyman down, and can create leaks, failed joints, damaged equipment, or safety hazards.
