The Ketuo Usurper SW is a premium folding knife created in collaboration with designer Derek Wedge of Sevr Sevn. Combining aggressive geometry with practical everyday performance, the Usurper features a compound-ground M390 tanto blade and Ketuo’s distinctive “Dragon Shard” titanium handle.
The 3.43-inch blade is made from Böhler M390 stainless steel, providing excellent edge retention, corrosion resistance and wear resistance. Its compound hollow grind combines a reinforced tanto tip with efficient cutting geometry for both controlled precision work and demanding everyday tasks.
This SW version features a rugged stonewashed finish on both the blade and titanium handle. The stonewashing creates a low-maintenance appearance that helps disguise fingerprints, light scratches and normal signs of use.
The precision-machined 6AL-4V titanium handle features Ketuo’s angular Dragon Shard milling, providing both a distinctive industrial appearance and additional grip. Contrasting gold-tone hardware adds visual detail to the subdued stonewashed finish.
A front flipper and large blade slot provide multiple deployment options. The blade rides on ceramic ball bearings for smooth, fast action, while a stainless-steel liner lock secures it during use.

Why You’ll Like It
The Usurper SW offers an excellent balance of premium materials, unusual styling and practical everyday performance. Its M390 blade provides long-lasting cutting ability, while the compound tanto grind delivers a strong tip without giving up useful slicing geometry.
The deeply machined titanium handle provides considerably more visual character and grip than a plain titanium frame. Its full stonewashed treatment also makes this version especially suitable for regular carry because minor wear blends naturally into the finish.
