Overview

The MTPEN is a 3-piece knife set from the brand Unique, with each piece listed at 0.07 kilograms, about 2.5 ounces. That weight points to small, pen-style or pocket-sized knives rather than full size fixed blades.

Pen-style knives are built for light, everyday cutting rather than outdoor or survival use, and a 3-piece set at this weight suggests a small EDC or utility grouping. No seller description or blade length is given, so material and blade type are not confirmed here.
