It will also flawlessly sharpen double-bevel or single-bevel 15 degree class knives. It’s advanced, flexible spring guides provide accurate control of the sharpening angle insuring ultra-sharp edges quickly and easily. The Model 15 received top marks for best performance and best edge in Cook’s Illustrated’s 15º knife sharpener evaluation in the July/August 2015 issue. It received the “Highly Recommended” rating and the magazine noted that “with diamond abrasives and a spring-loaded chamber that precisely and gently guided the blade, it purred with perfection, consistently producing edges that were sharper than on brand-new knives from edge to tip.” Also noted was the Trizor XV’s “big perk: it can convert a 20-degree edge to a sharper 15 degrees.” 3-Stage EdgeSelect® system for versatility in choice of edge for various cutting tasks Designed, engineered and assembled in the USA
