The Candiru is the smallest knife from the Esee collection. That only applies for the size, but not for the quality and durability. The blade is made out of 1095 carbon steel which ESEE uses a lot. It has sublime cutting properties and can be sharpened easily. Esee has added a black powder coating to the carbon steel blade which helps a lot against corrosion. We do advise to store the knife dry and grease/oil it before putting it away. Just to be sure!
