Sobral Brothers / CAS Knives - 8" Andes Fighter Bowie San-Mai - PRIVATE COLLECTION - handmade knife
KNIFE WITHDRAWN FROM PRIVATE COLLECTION
* Origin: Withdrawn from a private collection, previously purchased
* Condition: Never used, never removed from its sheath, never displayed; as it is a carbon blade and has remained in its sheath for a long time, it has unfortunately developed small spots of oxidation on the blade, which can be easily removed with a potential re-sharpening. However, it is not possible to remove the oxidation present on the passivating oxidation of the hamon. The price at which it is offered takes into account these aesthetic details, which in no way compromise its potential practical use.
* Available on the market: unique piece, entirely handmade
* Sharpening: Factory
* Marks on blade: small spots of oxidation, some potentially removable (those on the edge and tip of the blade)
* Marks on handle: None
* Box: Sold with burgundy velvet case
* Sheath: Like new, never used and never worn
* Manuals, Certificates, and Warranties: -
* Checked and Certified by our in-house laboratory
CAS Knives is the brand of Argentine brothers Claudio, Ariel, and Marcelo Sobral, artisans specializing in custom knives.Claudio, who has been passionate about weapons since he was young, started working in a weapons factory at the age of 16, acquiring skills in forging and metalworking. In 2005, together with Ariel, he turned his passion for knives into a full-time business, which Marcelo joined in 2013, dedicating himself to the creation of sheaths.
Renowned for their use of the San Mai technique, which combines aesthetics and functionality, the Sobrals combine creativity, craftsmanship, and dedication, working from their workshop in José León Suárez, near Buenos Aires.
