NDEFAFLY Cold Knife Bent Windscreen Removal Blades 2PK — Angled Auto Glass Cut Blades for Adhesive & Sealant

NDEFAFLY Cold Knife Bent Blade 2PK is a pair of angled windshield removal blades made for cutting through adhesives, sealants and rubber seals around car doors and windscreens.

These bent cold-knife blades are built to reach tight corners and scrape deep-penetrating adhesives without heat, helping technicians and DIYers free glass and trim safely. Sold as a two-pack, each blade is shaped to provide leverage and access behind seals where flat scrapers can’t reach. The blades are intended for use with manual holders or compatible pry tools to cut bonding materials like silicone, caulk, urethane adhesive and general sealant.

How do these bent blades make windshield removal easier?

The angled profile is designed to slip between glass and seal, letting you sever bonded materials with controlled strokes instead of relying on heat or power tools. That reduces the risk of cracking or chipping adjacent glass and trim. The 2PK gives you a spare blade or a matching pair for both sides of the vehicle.

• Angled tip reaches corners and behind seals for precise cuts
• Manual cold-cutting avoids heat stress on glass and paint
• Two blades included for backup or multi-station work

What materials can these blades cut or scrape?

They were made to remove soft bonding compounds and buildups: penetrating adhesives, automotive caulking, silicone sealants and similar materials that resist flat scrapers. They also work for scraping paint edge residue, adhesive beads and sealant in tight seams. Avoid using on hard metals or materials that could damage the blade edge.

• Effective on urethane adhesives, silicone and caulks
• Good for scraping adhesive residue and paint flaking
• Not intended for cutting hardened metal or abrasive substrates

How should I use and maintain the cold knife blades safely?

Use steady, controlled strokes while keeping the blade edge away from bare fingers and the windshield surface to prevent nicks. Pair the blades with a suitable handle or pry tool that accepts bent blades, and replace them when edges dull. Clean off adhesive residue after use and store blades dry to prevent corrosion and maintain cutting performance.

• Use with proper holders and wear cut-resistant gloves
• Wipe blades clean after each use to remove adhesives
• Replace when the cutting edge shows significant wear

Who is this for: These NDEFAFLY Cold Knife Bent Blades are aimed at automotive technicians, glass installers, collision-repair shops and experienced DIYers who remove windscreens, door glass and sealed trim. If you regularly deal with bonded glass, caulk or sealant in tight areas, the two angled blades provide reachable access and a reliable backup, letting you work more precisely without heat or power tools.
