Overview
The Slice 10400 pairs a ceramic blade with a glass filled nylon handle, measuring 6.97 inches overall and weighing 96 grams. Ceramic construction means the edge will not rust and holds up differently than steel under everyday cutting.
Category data lists this as a Knifes entry and the title confirms Knife, so this reads as a cutting tool rather than the sheath or holster that a mislabeled category might otherwise suggest. Ceramic blades are harder than steel but more brittle, so prying or twisting cuts is not something the material is built for.

Who it's for
Works for buyers who want a lightweight, corrosion-proof cutting tool for boxes, packaging, or light craft use. A ceramic edge is more prone to chipping under heavy-duty or prying work than steel, so this is not the tool for that.
Strengths and trade-offs
Drawn from this product's published specifications.
- Ceramic edge resists rust
- Lightweight at 96 grams
- Backed by 4,926 reviews at 4.6 stars
- Ceramic is more brittle than steel under twisting force
- Not built for prying or heavy-duty cutting
Performance notes
Ceramic edges cut cleanly through cardboard and light materials and resist the rust that steel blades develop over time, but the same hardness that keeps the edge sharp longer also makes it more prone to chipping if flexed or dropped on a hard surface.
