The Excalibur is what happens when a critic finally builds the thing he has spent years reviewing. Kunwu Knives developed it with Metal Complex, and the result has become the design flagship of the Kunwu collection: an overbuilt folder that still carries svelte, now grown into a three-build family.
The original Excalibur MC runs Uddeholm Vanax at 60 to 61 HRC on a 3.58 inch drop point with a milled fuller, a crowned spine, and thumb studs that pull double duty as external stop pins, the kind of engineering detail that built its reputation. The Verta Excalibur brings the same profile to Böhler Elmax and Kunwu's spine-side Verta Lock in contoured titanium or carbon fiber, and the Compact Verta Excalibur downsizes the pattern for lighter rotation. Our breakdown of how the major knife steels compare covers what separates Vanax from Elmax in daily use.
Metal Complex, the reviewer whose hands have logged thousands of production and custom knives, co-developed it with Kunwu as a deliberate distillation of the best design decisions he has handled, and the community treated the launch accordingly, with the November 2025 Verta Lock run selling through on pre-order. If the formula appeals but you want a bigger harpoon blade behind the same mechanism, the Kunwu Gringo runs it too.
