Vosteed A3520 Parallel 154CM

Inspired by the ideas explored in the book Parallel Universes and the Deep Laws of the Cosmos, the Vosteed Parallel is a sleek, ultra-thin folding knife designed by Yue Dong. Built for effortless everyday carry, it features a remarkably slim 7.1 mm titanium handle and weighs just 2.36 oz, making it exceptionally pocket-friendly without sacrificing strength. Precision CNC-machined Grade 5 titanium provides a refined balance of durability, lightness, and tight tolerances, while added jimping at the handle end enhances grip and control during use.

The knife is equipped with a 2.9-inch reverse tanto blade crafted from 154CM steel—an alloy famously popularized in the knife world by Bob Loveless. Originally developed for turbine engine bearings, 154CM offers excellent hardness, corrosion resistance, and wear resistance for reliable cutting performance. Paired with a smooth caged ceramic ball bearing pivot and a secure crossbar lock, the Parallel delivers crisp deployment, precise slicing capability, and a lightweight yet capable EDC experience.
