Fox Knives Vulpis 130-S4 CF

Fox Vulpis 130‑S4 CF – Compact M390 Slipjoint Multi‑Tool (4-Function)

The Fox Vulpis 130‑S4 CF is a refined, multi-functional version of the classic Vulpis line, made in Maniago, Italy. This premium slipjoint pocket knife features a 55 mm Wharncliffe blade crafted from Böhler M390, a high-end stainless steel known for superb edge retention, corrosion resistance, and hardness (59–61 HRC).

Alongside the main blade, the Vulpis 130‑S4 CF integrates four additional functions into its slipjoint design: a cap lifter, flat screwdriver, mini pry bar, and a compact saw. These tools are discreetly folded into the handle, offering essential utility in a minimalist form.

The slipjoint mechanism opens with a nail nick and uses spring tension rather than a locking system. The handle is made from 3K carbon fiber (lightweight, rigid, and visually striking), giving the knife a modern and durable feel.

Compact in design and easy to carry, the Vulpis 130‑S4 CF is ideal for EDC enthusiasts who appreciate a traditional mechanism blended with premium materials and tool versatility.
