Product Description

The Heretic Hydra V4 OTF H406-6A-CF/FTI pairs a 3.6-inch 20CV blade with a carbon fiber handle set off by flamed titanium accents, bringing Bohler's extreme-wear stainless to Heretic's Hydra automatic platform in a distinctive premium material combination.

20CV is Bohler's powder-metallurgy stainless steel, sitting in the same high-performance family as M390 and CTS-204P, extremely high chromium and vanadium content give it edge retention that rivals or exceeds CPM-S30V and approaches the ceiling set by CPM-S90V, along with strong corrosion resistance. The tradeoff is a more demanding sharpening requirement than mid-tier PM steels like CPM-154 or CPM MagnaCut, quality diamond stones or CBN abrasives work best on 20CV's dense carbide structure.

Carbon fiber handle scales are prized for being extremely light relative to their strength and for their distinctive woven-fiber look, giving the Hydra V4 a lightweight, premium-feeling frame.

Flamed titanium is a heat-coloring process applied to titanium hardware, controlled heat application produces a vibrant, often multicolor pattern of blues, purples, and golds that varies piece to piece, it's a popular premium accent treatment on pivots, hardware, and other small components.

The out-the-front mechanism fires the blade straight out of the front of the handle at the push of a button and retracts it the same way, no manual flip, thumb stud, or disengage step required.
