Warthog V-Sharp A4 Knife Sharpener with Diamond Rods

The Warthog V-Sharp A4 is a professional knife sharpening system built around a patented V-Sharp mechanism that lets you fine-tune blade angles with exacting precision. Four adjustable settings of 15, 20, 25, and 30 degrees cover everything from thick machetes, hunting knives, and bushcraft blades to delicate filet, sushi, and high-end kitchen knives, so the same unit handles both heavy outdoor tools and thin kitchen cutlery.

The spring-loaded hones sharpen both sides of the blade simultaneously, and a few quick strokes restore an edge. The unit pairs a metal frame and solid rubber base with a durable powder-coat finish, and ships with a 325 grit natural diamond hone plus a hardened hone steel for finishing. Additional 270, 325, 600, 1000, and ceramic hones are available separately.

Materials & care

The sharpener has a metal frame with a solid rubber base and a durable powder-coat finish. The spring-loaded hones sharpen both sides of the blade at once. Replacement and additional hones in 270, 325, 600, 1000 grit, and ceramic are available separately.

How to use

Select one of the four angle settings - 15, 20, 25, or 30 degrees - to match the blade. Use 30 degrees for larger, thicker blades such as machetes, forged blacksmith, and bushcraft knives; 25 degrees for most pocket knives; 20 degrees for thinner kitchen knives; and 15 degrees for fine filet and Japanese sushi knives. Draw the blade through the spring-loaded hones, which sharpen both sides simultaneously, then finish with the hardened hone steel.
