New! Doble O Knives: exclusive, handcrafted, and design-driven!

Doble O Knives, founded by Mexican knife maker Ovidio Calvet and based in Mexico City, specializes in high-end handmade knives for bushcraft, survival, EDC, and the kitchen. The brand stands out for its unique combination of premium materials, artisanal production, and artistic designs. As a result, the knives are cherished by collectors, designers, and fans of tactical luxury. Unlike many other knife brands, Doble O does not focus on mass production, but on small, exclusive runs, often just a few pieces per model, all crafted entirely by hand.

The Vision of Doble O Knives

At Doble O Knives, everything revolves around quality, functionality, and aesthetics. Each knife combines robust construction with refined finishing and perfect balance. Despite their exclusive character, the knives are designed for intensive use—a rare blend of performance and beauty. Models are often released in limited runs and sold through lotteries or waiting lists, further enhancing their exclusivity. Product lines, such as the popular Ronin series, are regularly updated with new versions in various material combinations such as Sleipner steel, G10, Micarta, and special coatings like Cerakote.

Doble O Knives Ronin 2.1

In 2025, Doble O Knives introduced the Ronin 2.1, a refined version of the Ronin 2.0 from 2024. Designed by Ovidio Calvet, in collaboration with Pablo Movilla, the 2.1 builds upon the signature modified tanto blade with three functional cutting edges: a hollow grind for precision work, a flat grind for powerful chopping and push cuts, and a false edge for improved penetration. The new version offers enhancements in steel type, coatings, markings, ergonomics, and carrying comfort. A striking addition is the luxurious leather sheath with multi-clip, featuring an integrated Kydex ring for accessories such as a firesteel or compact flashlight (1.4 cm opening). Inside, there is an extra Kydex liner that prevents rust formation and ensures firm knife retention without compromising the classic look of leather.

History of Doble O Knives

After more than 35 years of collecting knives and 7 years of experience as a knife maker, Ovidio Calvet decided to turn his passion into a professional brand. From his workshop in Mexico City, he launched Doble O Knives, which appeared on the radar of enthusiasts worldwide in early 2020. The real breakthrough came around 2023–2024 with models such as the Ronin and the Odisey X. Today, Doble O Knives is a well-established name in the high-end segment of the knife world, where uniqueness, craftsmanship, and rarity always take priority.
