ULTRA SAFE 48Concealed blade safety knife

Description

The Tortoris US48 is a safety knife with a unique dual-edge blade: mounted on one side but sharpened on both, making it the only knife in its class that cuts both toward and away from the body — giving users flexibility no comparable knife offers.

Its 4.4 mm cutting opening is wider than on fully concealed designs, letting it handle thicker materials with ease — a clear advantage over the fully enclosed Tortoris US43 and US53 for heavier cutting tasks. Cutting performance is excellent throughout, with very low cutting resistance for effortless use and clean, precise cuts.

The blade guard is highly robust, holding up reliably even under heavy, repeated use. Piercing behavior is very good, letting the blade enter material easily from the side.

The US48 is best suited for users who value cutting versatility and the ability to handle bulkier materials — a specialist tool for tasks that call for more than a standard single-edge blade.
