The correct way to use a utility knife

‌ Grip ‌:

‌ Straight or large-scale cutting ‌: Place your index finger on the back of the utility knife and wrap your palm around the handle to apply force. ‌ ‌ Small or arc cutting ‌: You can easily hold the handle with your thumb, index finger, and middle finger like holding a pencil. This grip is freer and more flexible. ‌ ‌ Cutting direction and angle ‌:

‌ Straight-line cutting ‌: Start cutting from the farthest point and gradually move closer to avoid the blade extending too long, causing the tangent line to be skewed or the blade to break.
‌ Angle control ‌: The angle should be moderate when cutting. If it is too shallow, it will not cut through. If it is too deep, it will easily cut crooked. More practice can help you find the "golden angle". ‌ ‌

Usage tips and precautions ‌:

‌ Use a ruler to assist ‌: First, fix the blade on a straight line, then place a ruler to cut to avoid errors.
‌ Avoid blade dulling ‌: Check the blade regularly to see if it is sharp. A dull blade not only affects the cutting effect but may also cause danger. If the blade is dull, you can use the auxiliary groove at the rear end to break it. Avoid pressing it directly on the edge of the table to break it to prevent the blade from splashing.

‌Safety measures‌:

‌Stay focused‌: Stay focused when using, do not swing the knife at will to avoid injury.
‌Correct posture‌: When holding the knife, apply force evenly with your fingers, push the blade forward, and avoid prying it upwards to cause loss of control.
