Collection: Utility Knife Blades

The best utility knife blades for your application will depend partly on your priorities and partly on the material you’re cutting. Because safety is a primary concern for most of our customers, our tools ship with a rounded-tip blade installed. Pointed tips are not required to pierce most materials and rounded tips guard against accidental puncture wounds.

Some materials, however, make it difficult to initiate the cut with a rounded-tip blade. In this case, the best utility knife replacement blades will be the 10528 pointed-tip blades. It’s worth noting that, while these blades do fit in our 10591 Manual Utility Scraper and our 10593 Auto-Retractable Utility Scraper, the tip shape is unlikely to make a practical difference, since the user is scraping with the entire blade edge and not initiating cuts.

Utility knife blade replacement won’t be required for a long time when you use Slice; our blades outlast standard metal blades (by up to 11 times longer). We use extremely hard zirconium oxide and careful blade design to ensure exceptionally long wear resistance.

Ceramic blades differ from manufacturer to manufacturer. Ceramic blades don’t all feature the same material composition and traditional ceramic blades mimic the thin, sharp edge popularized by metal blades. This makes other ceramic blades, be they for kitchen or industrial use, prone to the chipping that will destroy the blade edge, which can compromise their longevity.

If you’re wondering how to dispose of utility knife blades from Slice, there are two things to keep in mind: sharps boxes and recycling. While most people don’t have sharps boxes at home, safety regulations typically require businesses that use blades to provide sharps disposal boxes in order to minimize handling injuries. A finger-friendly^® Slice utility knife blade has an edge that’s much safer to touch than overly sharp metal or ceramic blades. In fact, some companies have chosen to forego cut-resistant gloves after switching to Slice. When it comes to our rounded-tip blades, they pose such a small risk of handling injury that no special utility knife blade holder or sharps box is not required for disposal. For our pointed-tip blades, the decision is up to the company, as a pointed tip does pose a puncturing risk.

As for recycling, Slice blades are made from zirconium oxide, which is 100 percent recyclable. If you find that there are no advanced ceramic recycling facilities in your area, feel free to mail your used blades to us at our global headquarters in San Jose, California, and we’ll recycle them for you.

This will depend on the cutting depth you need. Our utility knife blade dimensions allow for a deeper cut than our box cutter blades. The benefit of a shorter blade is that you reduce the risk of injury and damage to a package’s contents. If your material is thicker, or the shape of the box cutter is impractical for your applications, though, it makes sense to try our utility knives.

Slice^® utility knives are offered in a variety of options based on use and safety features. For example, some have auto-retracting blades to aid in preventing accidents when the tool is not in use. Some specialize in cutting specific material like foam, batting or insulation. It’s important to consider the tool’s particular use before making your selection.

We’re confident enough to say that if you need an effective tool and safety is your top priority, we offer the best utility knife blades to balance those needs. Over half the Fortune 1000 companies use Slice to successfully reduce injuries and lower costs. Our blades have a number of safety features, but the main safety adaptation is the design of our proprietary finger-friendly edge. This edge has a double grind intended to shorten the cutting zone and widen the cutting angle. In this way, it starts at a safe sharpness. And because of the material we use and our unique design, the blade stays at that sharpness up to 11 times longer than metal blades. Because other ceramic blades mimic the thin, over-sharp design of metal blades, they are similarly dangerous. In fact, ceramic blades are often even sharper than metal blades. One thing is certain: no other company uses the same safety edge as Slice, which cuts effectively but is safe to the touch.
In addition, our blades are

• Non-sparking
• Non-magnetic
• Non-conductive
• Chemically inert
• Safe up to 1600 degrees Celsius
• Never rust

The following tools ship with the 10526 rounded-tip utility knife blade, but are also compatible with the optional 10528 pointed-tip blade:

• 10550 Manual Utility Knife
• 10554 Auto-Retractable Utility Knife
• 10558 Smart-Retracting Utility Knife
• 10591 Manual Utility Scraper
• 10593 Auto-Retractable Utility Scraper
• 10585 Manual Carton Cutter
• 10562 Folding Utility Knife

In short, no. We’re committed to no-tool blade change designs in all our tools. Our scrapers extend to a blade-change position when you press down on the “lock” tab. For our utility knives, users remove the door at the back by rotating the slot to an unlocked position, extending the blade, then sliding the blade lock knob into the central unlocked position.

To change the Carton Cutter blade, expose the orange housing by sliding it out of the metal sheath. Open the housing cover lengthwise, as you would a book, to expose the blade, which easily lifts out. As for the Folding Utility Knife, lock it in the fully extended position. Press the oblong button at the tip of the handle and, at the same time, pull the blade out of the casing. It’s that simple.

In this way, the utility knife blades can be reoriented for left-handed users, flipped for a fresh edge, or replaced easily.
