Love them or hate them, Rizzuto Estileto Milano and Korizzy knives are classic autos made in large quantities over time. Made in the 1960s and 70s and smuggled through US ports of entry or ordered through magazine ads, rizzutos were some of the first automatic knives many of us had growing up. They are certainly still around and enjoyable to collect.

Here we try to capture all of the designs by country, variations made and identify the characteristics which define those models, with an eye towards chronology. Towards getting after the order in which the models were produced, there is supposition, logic and guess work arising from a lot of research that we hope is correct. If you know something not reflected here or have a rizzuto knife not included, please let us know.

No matter what, we hope you find this guide useful, grist for thought and a helpful aid. That is really why this is here.
