Cold Steel Magnum Tanto IX VG-1 SAN MAI Prototype - Lynn Thompson's personal collection – Like-new condition

This example of the Cold Steel Magnum Tanto IX is offered as an unmarked prototype from Lynn Thompson’s personal collection. It features the characteristic silhouette of this large tanto: a long blade with clean, taut lines, an oval guard, and a black handle topped with a contoured metal pommel.

Its most noticeable feature is the absence of any markings on the blade; the surfaces remain entirely unmarked, revealing the grinding work and the differences in finish between the flat surfaces, the main bevel, and the tip.

The American tanto profile features a sharp angular break between the main cutting edge and the tip. The satin finish accentuates this geometry, with different polishing directions depending on the surface. The overall design maintains a understated appearance, which is particularly striking on a blade of this length.

The black handle features a fine raised grid pattern and a flattened oval cross-section. The metal guard provides support at the front, while the tapered pommel features a lanyard hole. The contrast between these light-colored metal parts and the dark handle remains true to the classic aesthetic of the Cold Steel Tanto family.

The knife is in mint condition; its provenance from Lynn Thompson’s personal collection and its identification as a prototype are the key factors contributing to its collectible value.

The production model used as a reference is the Magnum Tanto IX 13MBIX in VG-1 San Mai III. However, the absence of markings on this specimen alone does not allow for certification of the steel grade or assignment of a specific year of manufacture.

Tellknives Review:
We particularly appreciate the visual appeal of this piece. The absence of a logo gives the blade an unusual purity and allows the lines of the Magnum Tanto IX to be fully appreciated.

For a Cold Steel collector, its appeal goes beyond that of a simple finish variation: it lies in its status as a prototype and its stated provenance. Nevertheless, we prioritize an accurate description that distinguishes this information from what can be observed in the photographs. Without technical documentation specific to this specimen, we cannot assign an exact date, confirm the steel composition, or specify the production quantity.
