Things You'll Need
Carpet loop cutter
If you prefer to complete projects yourself rather than spending the money to hire professionals, then perhaps you have considered installing carpet as your next home modification project. A carpet loop cutter, also known as a loop pile cutter, cuts carpet while minimizing fraying and other damage. For best results, read the installation guide provided by the manufacturer of your carpet to see if a carpet loop cutter is the right tool for your carpet.
Measure the carpet to see where the cut needs to be made.
Turn the carpet over or fold it back to see where the rows are. The rows are the areas between loops in the carpet. Though you can't see them from the top of the carpet, on the back you will notice "ridges" and "valleys". Cut along a valley line to minimize fraying.
Place the "mouth" of the cutter over the carpet so the blade and the "nose" of the cutter are between rows of carpet loops. You may find that it is helpful to "mark" the line you will be cutting by separating the carpet loops by running a pocketknife along the line you will cut. Most loop cutters are configured so the blade cuts through the bottom, or back, of the carpet.
Push the carpet trimmer forward using your dominant hand. Keep your non-dominant out of the way of the carpet trimmer for safety purposes.
Check periodically to make sure the nose of the cutter is still between rows.
If cutting becomes difficult, remove carpet build-up from the blade or replace it.
Use proper safety precautions when working with the sharp blade on the cutter. Thick leather gloves should be warn to prevent cuts. Keep your hands away from the blade, and always move the cutter away from your body while cutting.
