Every tradesperson needs a set of replacement utility blades in their toolkit to ensure that their utility knife is sharp and in pristine working condition. When a utility blade becomes dull, it can pose a potentially serious safety risk.
As many who work with knives know, from chefs to artisans, a blunt knife is more dangerous than a sharp one. Here are some of the safety risks dull utility blades pose and how they can be avoided:
A dull knife requires extra pressure to create a satisfactory incision. However, putting extra force on the blade increases the likelihood that the blade might slip, which could lead to accidental cuts or injuries, especially to the hands and fingers.
To avoid this, regularly inspect the blade before use. If you notice a decrease in cutting efficiency, replace the dull utility blade immediately with a fresh spare.
Your blade should cut smoothly with moderate force. If you find yourself applying excessive force, you know that there is a problem.
Dull blades don’t cut as cleanly as sharp blades do, resulting in jagged or uneven cuts. Not only can these jagged edges prove to be a safety hazard, but they can also cause frustration for the blade wielder, leading them to apply more force, which increases the chance of the blade catching or binding in the material unexpectedly. This can result in injuries.
Ensure that you’re using the right kind of blade for the material at hand. As such, you should not only have both smooth and serrated replacement blades available that you can switch out, depending on the need, but also have these spares on hand so you can swap out a dull blade to ensure safe and precise cutting.
When a utility blade is worn down, it becomes more prone to chipping or breaking when put under pressure. Broken blades can be dangerous. If your blade shows any signs of damage, such as nicks or bends, it’s advisable to replace it as soon as possible with a fresh, sharp spare, and to always wear safety glasses and gloves to protect your eyes and hands when cutting.
Because you need to apply more force when using a dull blade, you’re more likely to suffer muscle fatigue and strain in your hands, wrists and arms over time.
Long-term use of a dull blade can actually result in serious long-term harm from repetitive strain injuries. The solution is to always ensure your blade is sharp and switch it out with a fresh blade if you are exerting yourself too much during cutting tasks.
