The Rubytec Ceramic Mini Foldable Knife is an ultra-lightweight, compact knife that belongs in every sailor’s kit. Small enough to fit easily in a jacket or trouser pocket, yet powerful enough for real onboard use, this knife is made with a ceramic blade and features a practical lanyard for quick access.

Ceramic blades stay sharp significantly longer than steel, are highly hygienic, and are not affected by salt, oil, or acidic substances. Made from zirconium oxide, a material second only to diamond in hardness, the blade delivers excellent cutting performance while remaining rust-free and easy to maintain.

This knife cuts Dyneema® effortlessly, making it an essential tool for trimming lines, emergency situations, or everyday tasks on board. Compact and lightweight, it is also ideal to keep in your buoyancy aid for quick access when you really need it.

The folding mechanism can be adjusted using stainless steel screws, allowing you to fine-tune the opening resistance to your preference.
