The new dim grey titanium Vosteed Thunderbeast is the latest evolution in a line of knives that blends paleontology with Native American mythology. Following the Thunderbird and Ankylo, it honours the strength of Lakota tradition with a modern, sleek design. Built for those who demand power and precision, Thunderbeast delivers both style and performance, making it a true beast in your hand.

The whole knife leans forward with a “diving” profile and multi-faceted geometry running from tip to tail, giving it motion even at rest. A 3.49" acid wash and stonewash reverse tanto blade with a small top swedge adds three‑dimensional character and a techy, purposeful look. The handle flows in smooth curves, shaped into four main planes with soft transitions, so it feels sculpted rather than stamped.

Thunderbeast pairs a high‑performance M390 blade with a full titanium handle for the ideal mix of strength, edge retention, and carry comfort. 

The handle is CNC‑milled with four facets, all edges carefully chamfered, and an extra 0.5 mm bevel at the tail for added depth. 

Inside, the upgraded Vanchor Lock delivers secure, repeatable lockup with a low, satisfying thunk when the blade snaps home—serious hardware wrapped in a sleek, modern shell.

A large thumb hole opens up the profile and makes slow‑rolls and flicks effortless. You get three deployment options—thumb hole, front flipper, and back flipper—backed by well‑placed jimping for secure traction. 

The 3D CNC-machined titanium pocket clip mounts tip-up with hidden screws, mirroring the handle's facets for an ultra-clean look

A full, recessed lanyard tunnel keeps paracord options without breaking the silhouette.

Thunderbeast is one of our biggest titanium folders, but careful tuning of blade and handle weight keeps the balance point right where it should be. Open or closed, the proportions stay harmonious, and the knife feels lively in hand, not bulky. The ergonomics, chamfered edges, and secure lock make hard cuts feel controlled, while the deep, low opening sound and smooth action make every flip quietly addictive.
