The Warthog V-Sharp A4 is a precision knife sharpening system built around a patented V-Sharp mechanism that sharpens both sides of the blade simultaneously. Its metal frame, solid rubber base, and durable powder-coat finish keep the unit stable during use, while spring-loaded hones follow the edge for consistent results.

Four adjustable angle settings—15°, 20°, 25°, and 30°—let you match the edge to the blade, from thick machetes and bushcraft knives at 30° to filet and Japanese sushi knives at 15°. The included 325 grit natural diamond hone and hardened hone steel handle sharpening and finishing, and additional 270, 325, 600, 1000, and ceramic hones are available separately.
