Dmitry Sinkevich is a Russian knife designer known for clean geometric aesthetics and precise, considered proportions. The Oligarch is his collaboration with Pro-Tech — a handle-heavy design with a thick aluminum frame and a relatively compact blade that gives the knife a substantial, authoritative feel in the hand. Pro-Tech manufactures the Oligarch at their facility in Placentia, California to Sinkevich's design specification.

The DS103-T.Blue uses CPM MagnaCut with a DLC black finish. MagnaCut was developed by Crucible Industries to outperform conventional blade steels across all categories — M390-level edge retention and wear resistance combined with corrosion resistance that rivals dedicated stainless steels. The DLC coating adds surface hardness and completely eliminates blade glare. In a sheepsfoot profile at 0.13 inches thick with a compound grind, MagnaCut delivers its performance across the full edge length where a sheepsfoot does most of its work.

A sheepsfoot blade has a flat cutting edge with a curved or dropped spine that meets the edge at the tip, creating a blunt, rounded tip with no point to speak of. This geometry maximizes the usable edge length and makes the blade exceptionally precise in controlled slicing — food prep, material cutting, rescue work — while reducing the risk of unintentional tip puncture. Sinkevich's choice of sheepsfoot on the Oligarch emphasizes the knife's slicing capability over tip work, which suits the design's civilian EDC and professional utility positioning.

The Pro-Tech Oligarch is a push-button automatic knife with a 3.25-inch blade. Automatic knife laws vary significantly by state and locality — some states permit them freely, others restrict by blade length or require permits, and some prohibit them entirely. Knifeworks recommends verifying your local and state laws before purchasing or carrying. A compliance form is required at checkout.

The Oligarch's weight comes from its thick aluminum handle frame — at 0.5 inches, the handle is meaningfully thicker than most production folding knives and is designed to fill the hand rather than disappear in it. This is a deliberate design choice by Sinkevich — the Oligarch is built to feel substantial and authoritative in the grip. The handle-heavy balance and the aluminum construction contribute to the weight. For buyers who want a knife that feels like a full-size tool rather than a lightweight EDC folder, the Oligarch's weight is a feature.

The Oligarch DS103-T.Blue measures 7.125 inches overall when open with a 3.25-inch blade. Closed length is 4.879 inches and handle thickness is 0.5 inches. It weighs 5.4 oz. The tip-up right-hand clip is finished in black to match the hardware and DLC blade.
