Extrema Ratio - made and designed in Italy

Extrema Ratio are beautifully designed knifes,

all highly engineered, made in Italy.

I own all three of these models:

Extrema Ratio MF0

Extrema Ratio Fulcrum C. Testudo

This one is not made by Extrema Ratio,

but is it made in Italy by Fox, designed by

American martial arts practitioner Rob Walker
