Baton Rouge, LA (October 13, 2022)- New for 2022 at Warthog Sharpeners is the A4; a revamp of the legendary Warthog V-Sharp system used in the Classic II and the original Classic sharpener. However, they’ve taken it a step further in true Warthog style.

Warthog Sharpeners has added a 15-degree angle to its new A4 model, offering four settings to cover all the bases for your knife needs (15°, 20°, 25°, and 30°). Like the Classic II, the A4 is equipped with two 325-grit double-sided diamond rods and finishing steels that simultaneously sharpen both sides of the blade. The sharpener weighs about 1-pound and has a hand-crafted metal frame, sturdy rubber base, and powder-coated finish.

Changing Kitchen Trend

A recent phenomenon is knife manufacturers’ broad adoption of the 15-degree edge. The 15-degree edge exhibits less cutting friction, particularly when a thinner blade geometry is accompanied. This follows suit with Japanese chef/sushi knives, which have been utilizing sharp angles on their knives with excellent results. Contemporary Asian knives usually have a double bevel with a 15-degree angle on both sides. Among these knives are the Santoku and Nakiri. In the home kitchen, a 15-degree angle is perfect for modern chef knives. Use the other angles for heavier cleavers, pocket knives and EDC knives. Whether for your inner pro home cook or professional, the Warthog A4 covers all the bases.
