Overview
The Slice 10503 is a knife with a ceramic blade and glass filled nylon handle, measuring about 6.97 inches long and weighing 4.48 ounces, built for rust resistant everyday cutting.
Ceramic blades don't rust or corrode the way steel can, and they hold their edge differently, though the material is also harder and more brittle, meaning it can chip if used to pry or twist rather than cut cleanly through material. The glass filled nylon handle adds rigidity without the weight of a full metal build.
- Ceramic blade material
- Glass filled nylon handle
- About 6.97 inches long
- 4.48 ounces total weight
Who it's for
Fits users who want a rust resistant blade for straightforward cutting tasks like cardboard or packaging. Not a fit for anyone needing a blade for prying, twisting or heavy impact use, where a more flexible steel blade holds up better.
Strengths and trade-offs
Drawn from this product's published specifications.
- Ceramic blade resists rust and corrosion
- Lightweight at 4.48 ounces for daily carry
- Rigid glass filled nylon handle
- Ceramic blade is more brittle than steel
Performance notes
Ceramic holds an edge without corroding, which suits repeated cutting of materials like cardboard and packaging, but the material is harder and more brittle than steel, so it can chip if twisted or used to pry rather than sliced straight through. At 4.48 ounces, it stays light for extended one handed use.
