Frequently Asked Questions
Have questions about utility knife replacement blades? We’ve got answers!
Not all utility knife blades are interchangeable. There are a handful of different styles, such as straight edge utility knives versus breakaway blade models. All standard blades—typically about 61mm wide—should fit a standard utility knife.
However, if your knife has breakaway blades, you may need to check measurements or purchase the same brand as your knife to ensure a good fit. A loose blade can be a safety hazard, so making sure the pieces work together is vital.
Another consideration is self-feeding knife types since these will also take a specific type and size of blade. When in doubt, choose a package that comes with utility knives—and make a note of the blade style so you can buy replacements as necessary.
Most utility knife blades are not the type you can sharpen. However, some manufacturers do make blades that are reusable once you grind the edges down. Most are not, though, and trying to grind down an edge could result in injury or, at the very least, breaking the blade.
Manufacturers use rugged materials to make their blades, but most have a coating on them that will resist grinding. The idea is that the coating—or plating—helps keep the blade sharp. So, that won’t work out well if you try to sharpen the coating versus the material underneath.
What type of blade you need depends on both the model of knife you have and the intent of the cut. For example, if you’re planning to slice open envelopes, boxes, and other light items, a more economical blade may work just fine.
However, if you’re planning to cut through drywall, leather, rope, or another sturdy material, you should aim for thicker, more durable blades. Coated or edged blades may fare better when pitted against vinyl and drywall.
Breakaway blades are typically better for lighter duty, while standard, straight edges can often handle heavier-duty tasks. But repetitive cutting can still dull your knives, so keep an eye on the sharpness and swap them out when you notice resistance.
How often you should swap blades depends on a variety of factors. From what you’re cutting to how you’re cutting it, and how often, there’s no simple answer to how often you should change blades. But you’ll be able to tell when the blade dulls.
Comparing the first-day performance to a few weeks in will tell you whether the blade is becoming dull and if you should invest in replacements.
