The TwoSun TS223 in Black Titanium/Carbon Fiber is a large, feature‑packed folder designed by Jelly Jerry that delivers serious performance and presence. With an overall length of 8.19″, it sports a 3.43″ blade made from Böhler M390 stainless steel, hardened to about 60 HRC, and about 0.154″ (≈3.9 mm) thick. The handle is a mix of titanium and carbon fiber, with titanium having a black or grey finish, and the knife uses a frame lock mechanism for secure blade retention. It weighs approximately 4.73 oz (134 g), striking a balance between heft and usability. The TS223 uses quality bearings (KVT ceramic balls) for smooth action, and the blade finish is satin/CNC ground.
