How to Sharpen a Carpet Knife

Things You Will Require:

  • Carpet knife
  • A wooden frame or box
  • water
  • A tissue paper or soft towel

We will complete this whole sharpening process into easy three steps. Those are prepping the knife and stone, sharpening the knife, and testing the knife’s sharpness. Let’s get started.

Step 1: Prep the Knife and Whetstone

First and foremost, what you need to do is prepare the knife, stone, and wooden frame. Choose a flat surface. Put the Whetstone in the wooden frame or box type thing so that it doesn’t slip or stand firm while you are sharpening the carpet knife. And now, you are all ready to go another step.

Step 2: Sharpening the Blade

Now the process of sharpening the blade begins. Since you have set everything, let’s now sharpen the carpet knife blade. Start rubbing the blade to the Whetstone in a pull motion against the blade. Running the blade at a 20-25 degree angle is preferable. However, try every possible angle that can bring the best results.

After pulling some strokes, use some water to make it smoother and work nicely. You can do this a few times when water is gone.

If you ask the duration of the time- well, it may take 10-15 minutes depending on the user and instrument. Don’t leave one side untouched. So, keep your eyes on both sides of the blade and make sure to flip over in order to sharpen the blade perfectly. Be careful when you are running the blade on the Whetstone because there are examples of people getting hurt or injured during this process. After sharpening the blade, clean it with tissue paper or a towel.

After doing this, wash the blade and be ready to check whether it is sharpened enough or not.

Step 3: Test the Knife’s Sharpness

Paper Cutting Testing

Before packing up your instruments, you should run a test on the blade whether the blade is sharpened well or not. So, how to tell if your knife is sharp enough or not? Well, to test the knife’s sharpness, you need to do something.

First, find a piece of paper (newspaper, offset paper, or any paper). Hold the paper in one hand and the blade in the other. Now, try to slice the paper with the blade. If the blade can cut through the paper smoothly or a clean-cut, the carpet cutter blade is sharpened successfully.

Unfortunately, if you cannot cut the paper a clean-cut, try sharpening from this angle until you are able to. Besides, make sure that you are using a good quality Whetstone. Remember, some old piece of sandstone may wear down very fast and make matters worse.
