Chef's Choice Model XV
4 sourcesall derived

The Chef's Choice Model XV is a three-stage electric sharpener that converts blades to 15 degrees and refines them using diamond abrasives. Consumer Reports found this system creates a durable Trizor XV edge, while Helen Rennie noted the process takes about five minutes for an 8-inch knife but requires careful reading of instructions to manage burr detection correctly. Although cosmetic scratches may appear on blade surfaces during use, they do not impact cutting performance or structural integrity. This unit suits cooks seeking speed and precision without manual skill, though those unwilling to follow detailed procedural steps should look elsewhere.

Strengths
  • — Three-stage system allows conversion of knives to a 15-degree angle, sharpening, and honing in slots one through three.
  • — Produces a sharp edge quickly; an 8-inch chef's knife takes approximately five minutes total for the process.
  • — Controlled-angle design minimizes user error regarding blade angles compared to manual stone sharpening.
Watch-outs
  • — Initial setup requires reading instructions carefully to understand the specific pull-and-check technique for each stage.
  • — Cosmetic scratches may appear on the blade surface during use, though they do not impact sharpness or function.

The Work Sharp Rolling Knife Sharpener features a magnetic angle block with four settings and an ergonomic handle that keeps hands safe from the blade edge. Outdoor Life found it produced the sharpest edges in its group test, while GearJunkie noted the variable angles offer significant versatility over fixed-setting competitors. However, the included abrasive discs are single-sided only, meaning they cannot be flipped to extend their usable life once worn. This unit is best for users seeking smooth maintenance of standard kitchen knives but should look elsewhere if they need to repair severely damaged blades or sharpen very small pocket knives without elevation adjustments.

Strengths
  • — Includes a magnetic angle block with four distinct sharpening angles (15, 17, 20, and 25 degrees) to accommodate various blade styles.
  • — Outdoor Life found it produced the sharpest edges in its group test compared to other rolling knife sharpeners.
  • — Features a comfortable ergonomic handle design that keeps hands away from the blade edge during use.
Watch-outs
  • — The included abrasive discs are single-sided only, meaning they cannot be flipped over to extend their usable life once worn.
  • — Not suitable for repairing severely damaged knives or removing large chips from the blade edge.
  • — Small blades like pocket knives may not fit properly on the magnetic angle block without specific elevation adjustments.
