The knife is the flagship collaboration between Vosteed and R.S. Knifeworks (Rob Saniscalchi). The knife features a satin finished M390 Wharncliffe blade and titanium handles, and it also comes with a re-innovated locking mechanism - Top Liner Lock. The knife combines the best of both worlds- tons of fidget factors and a high level of lock strength. Different from Rob’s frame lock custom version, the knife utilized its own Top Liner Lock (patent pending), which is similar to a hybrid of insert-liner lock and Compression lock. The Top Liner Lock is intentionally designed to be strong and secure. When the knife is in the closed position, the lock bar is almost completely hidden from view. The standalone stainless-steel plate is firmly secured in a milled pocket inside of the TC4 titanium handle, and it is further reinforced by a solid TC4 titanium backspacer. When the knife is in open position, the lock bar will keep the blade in place and prevent the blade from any further rotational motion. Similar to other Vosteed knives, the knife is also equipped with multiple deployment options. The chamfered thumbhole and the low-profile flipper tab work well together, and the combo offers both great convenience and fun fidgetablity. The finger choil (also provide clearance for the Top Liner lock) and the jimpings further increase functionality and safety when more control over the knife is needed. This Vosteed knife is based on Rob’s highly sought-after custom knife. The blade is made from Böhler M390 and feature Rob’s bold signature compound grind. The bright version has a satin-finished blade; its handle, button, and pocket clip are stonewashed and then sandblasted; this version has a copper-colored aluminum pivot collar. To enhance the ease of operation and user experience, the features a CNC-milled TC4 titanium button. The height and travel distance of the unlock button are designed to reduce accidental unlock. Furthermore, the 3D milled titanium pocket clip offers both secured carry and sleek aesthetics.
