Piece of Metal of 100 years !! turned into Canary Knife !!

In this video I make a canary knife with a very old piece of steel, I don't know how old it is but from its appearance it seems that it is more than a thousand years old! I hope you enjoy this video as much as I enjoyed making this knife which was my first blade made from scratch.
History of the canary knife:
This knife or razor, also called naife, has its origin in Toledo and Albacete, where the Arabs continued to live after the reconquest. It was common for these knives to be marketed and that through the conquerors and merchants who came to the islands they were introduced to the Canary Islands around the 15th century. However, until the 19th century it was not considered that it was possible to speak of a Canarian knife as such, which, although it retained many characteristics of that of Toledo and Albacete, showed many other features of its own.
