Using a blue carpet knife is simple.

Hold the knife securely with the hand guard protecting you from carpet burns, extend the blade, and make precise cuts on the carpet.

Press the two red buttons on the handle to open the knife and access extra blades, replacing them as needed, and ensure the knife is securely closed and the blade retracted when not in use.

A blue carpet knife can be repurposed for various tasks, such as:

1. Crafting: Use it for cutting thick materials like foam board, leather, or heavy fabric in crafting and DIY projects.
2. Box Opening: Utilize it to open heavy-duty packaging, boxes, or crates with ease.
3. Flooring Installation: Employ it for precise cuts on linoleum, vinyl flooring, or other tough materials during installation.
