Slice 10404 Ceramic Replacement Blade — Finger-Friendly, Rounded Tip, 11x Longer Edge

Overview

Meet the Slice 10404 Replacement Blade, a ceramic option designed for everyday box-cutting tasks where precision and safety matter. Crafted from zirconium oxide, these blades stay cool to the touch, resist rust, and don’t require oil coatings. The rounded tip adds an extra layer of protection during quick cuts or delicate work, helping to keep hands and edges safer. The edge retention and smooth glide are noticeable as you transition from unboxing to packing and light trimming.

Key advantages

• Four dual-sided ceramic blades per package for extended use
• Edge life up to 11x longer than steel blades, depending on task
• Rounded tip reduces the risk of puncture injuries during handling
• Ceramic, nonsparking, non-magnetic, and rust-free—maintenance is simple
• One ceramic blade can replace many metal blades, potentially lowering replacement frequency and costs
• Blades are reversible, giving you two fresh edges from a single blade

Compatibility and practical use

These blades are designed for use with Slice cutting tools, including box cutters, pen knives, and the Slice Mini Cutter. They fit models SKU 10400, 10503, 10512, 10513, and 10514. When a blade dulls, flip to the opposite side for a fresh edge, reducing downtime and the need for frequent blade changes. The ceramic material provides a smooth, steady cut that many users find easier to control for routine packaging tasks.

• Compatible with Slice cutting tools for streamlined workflows
• Lightweight, finger-friendly design supports safe, controlled cuts

Giving back and real-world notes

A portion of Slice sales supports autism research at Lucile Packard Children’s Hospital — Stanford University, reflecting a commitment beyond tool performance. In practice, the ceramic edge offers low-maintenance operation: no rust, no oil coatings, and no magnetic interference, making it appealing for busy workspaces and hobby projects alike.

Note: Individual results vary by use case. The ceramic composition provides a distinct cutting experience that many users appreciate for box opening, packaging, and light trimming where edge retention and maintenance-free operation are valued.
