Description
The KB Vertigo KB258B combines modern engineering with refined craftsmanship, resulting in a premium folding knife designed for everyday carry, outdoor adventures, and tactical performance. Designed by Peter Carey, the Vertigo offers a perfect blend of precision, style, and functionality.
At its core is a 3.11-inch S35VN Wharncliffe blade, a top-tier stainless steel renowned for its edge retention, corrosion resistance, and toughness. The stonewashed finish provides a rugged, non-reflective surface that hides wear and enhances durability. The Wharncliffe shape is ideal for precision cutting, slicing, and utility tasks.
The handle features a gray titanium frame with striking Watermelon Sugar CamoCarbon fiber inlays, providing both lightweight strength and a visually stunning appearance. Riding on caged ceramic ball bearings, the blade deploys smoothly with a satisfying, controlled action, while the liner lock ensures secure and reliable blade lock-up during use.
Every component, including the clip, screws, and backspacer, is crafted from titanium with a matching gray finish, delivering a cohesive, premium aesthetic. Whether you're an EDC enthusiast or a serious user who demands high performance, the KB Vertigo is designed to impress.
