Safer Unboxing Tool
Slice Combo Box Cutter Pack with Safer Ceramic Blades Now 20% Off for Prime Members
The Slice Combo Pack — a mini and a heavy-duty box cutter in one bundle — is 20% off during Amazon Prime Day 2026, which runs through June 26. USA Today reports the deal applies exclusively to the Sage green colorway and is available to Prime members. At roughly $16 after the discount, it's one of the more practical deals of the sale.
The cutters use ceramic blades instead of steel. That one difference is why shoppers keep coming back. The blades are far less likely to cut skin, and independent testing by the Cutlery and Allied Trades Association confirmed they last 11.2 times longer than standard steel blades.
Ceramic Blades Are Safer and Last Much Longer
Slice uses Zirconium Oxide — a hard ceramic material — instead of steel. On the Mohs hardness scale, it scores 8.2. Steel scores around 5.0. That hardness is why the blade lasts so long. But Slice also grinds the blade at a double angle. That means it cuts through cardboard and shrink wrap easily, but disperses pressure when it touches skin. You're far less likely to get a nasty cut.
Sheboygan Press notes the blades handle tough jobs well — opening cardboard boxes, slicing plastic clamshell packaging, and cutting heavy shrink wrap. One longtime user said they had used the "tiny box cutter for years" before needing to replace the blade. That kind of longevity justifies the higher upfront cost compared to a cheap steel utility knife.
Prime Day Deal Is Limited to One Color and Four Days
The 20% discount only applies to the Sage green colorway of the Combo Pack. Other colors are full price. Amazon Prime Day 2026 runs from June 23 to June 26, so the window to grab the deal is short. York Daily Record confirms the promotion is tied to the four-day sale event.
The Sage green color is part of a "New Colors" push Slice launched in late 2024. The brand moved away from its traditional orange-and-black industrial look. Lifestyle editors at major outlets have called the new shades a way to make everyday unboxing feel less utilitarian. Whether that matters to you or not, the discount makes it worth a look.
Why Safety Officers and Shoppers Both Love This Tool
Slice founder TJ Scimone built the company around what he calls "finger-friendly" blades. He told an industry audience: "Shipping and receiving departments appreciate blades that open corrugated without damaging the merchandise inside, while safety officers love our finger-friendly blades." Big companies like Chevron have adopted strict no-open-blade policies — and Slice fits right in.
OSHA estimates the average workplace laceration costs $41,000 when you add up direct and indirect expenses — medical bills, lost work time, and liability. That figure helps explain why safety managers push for tools like Slice. For home users, the math is simpler: fewer trips to the bathroom to bandage a finger.
One Real Drawback Worth Knowing Before You Buy
Ceramic blades are hard, but they are also brittle. Drop one on a concrete floor and it can chip or shatter. Steel dulls slowly. Ceramic can fail all at once. Some heavy-duty users also say the "finger-friendly" grind requires slightly more force on thick or fibrous materials compared to a razor-sharp steel blade. For most household unboxing tasks, that won't matter. But it's worth knowing.
