How to use

Hold the cutting tool with a steady grip and use short, controlled strokes to cut or score plastics and adhesives. For opening housings, start at an access point and work gradually along seams to avoid damaging internal components. Use the tool to trim adhesive strips or tape by applying light pressure and making incremental cuts rather than attempting large, forceful cuts. Always direct the blade away from your body and sensitive components, and work on a stable surface with adequate lighting.

Usage recommendations

Use the Bernstein 2-123 in combination with non-metallic pry tools and ESD-safe tweezers for safer separation of delicate components. Replace the tool if the cutting edge becomes dull or damaged to maintain precision and reduce the risk of slippage. Store the tool in a dedicated repair kit compartment to protect both the blade and the devices being serviced.
