The Ketuo Ventr V4 is the definitive answer for the forward-thinking EDC enthusiast who demands elite, custom-tier materials in a compact frame but is tired of standard button locks that suffer from blade play or weak internal detents. Designed by Braden Sweeten and manufactured by Ketuo, this fourth-generation powerhouse represents the absolute pinnacle of the Ventr platform's evolution. Moving far past its budget-friendly G10 and carbon fiber predecessors, the V4 makes a massive leap into the ultra-premium realm. It marries an industrial Böhler M390 stainless steel blade with a heavily chamfered and contoured TC4 titanium frame, delivering a bulletproof, hard-use companion clad in a sleek, tactical blackout aesthetic.
Using this knife solves the frustration of carrying compact folders that feel flimsy under heavy pressure or lack proper mechanical security. It provides that "expert-to-peer" pride of ownership, incorporating Ketuo's specialized hybrid button liner lock. By combining the highly addictive, drop-shut action of an external button release with the deep structural stability of a traditional internal liner lock, this mechanism provides a rock-solid, vault-like lockup with zero structural play.
In a fast-paced everyday utility layout or rigorous outdoor environment, the Ventr V4 operates with absolute precision and speed. Riding on ultra-smooth ceramic ball bearings, the 2.80-inch modified sheepsfoot and clip point blade can be fired open instantly using the ambidextrous thumb slot, a satisfying reverse flick, or a swift button-release gravity flip. Once deployed, the high flat grind and 0.12-inch-thick blade spine focus razor-sharp slicing pressure while maintaining an incredibly predictable cutting feel. The rugged black stonewashed finish acts as a resilient armor coating, effortlessly concealing scratches from tough field tasks.
If your workflow transitions into heavy-duty piercing or intense pushing, a manual secondary toggle switch slides forward on the frame to completely lock the button in place, totally eliminating the risk of accidental lock disengagement. For carrying, the knife is equipped with a matching milled 3D titanium tip-up pocket clip. Furthermore, it features an innovative, removable titanium rear tail ring; keeping it attached gives you a dedicated lanyard anchor, while removing it lets users with larger hands seamlessly change the ergonomics and carry profile on the fly.
