Using a black/yellow utility knife with a spring-loaded retractable blade is simple.

Push the trigger forward with your thumb to extend the blade and make precise cuts on materials like cardboard or plastic, then release the trigger to retract the blade automatically.

Handle the knife with care and ensure the blade is fully retracted when not in use to prevent accidents.

A black/yellow utility knife with a spring-loaded retractable blade can be repurposed for various tasks, such as:

1. Crafting: Use it for detailed cuts in projects like model making, scrapbooking, or other art and craft activities.
2. Scoring: Employ it to score surfaces like drywall, paper, or cardboard for clean folds or breaks.
3. Opening Packages: Utilize it to efficiently open boxes, packaging, or sealed items without the risk of the blade remaining exposed.
