The Work Sharp Professional Precision Adjust Knife Sharpener transforms dull blades into razor-sharp tools with professional precision. This advanced system features a digital angle display that shows exact grinding angles in quarter-degree increments.
Built with a heavy base plate for maximum stability, the system includes six magnetic sanding plates ranging from 220 to 800 grit, plus ceramic and leather finishing options. The tilting function accommodates large blades whilst the magnetic holder secures smaller knives perfectly.
What makes this system special? The 180-degree rotating blade holder means you only clamp each knife once. Two O-rings limit the grinding path for consistent results every time. Works with kitchen knives, pocket knives and even serrated blades.
The system handles virtually all knife types including kitchen knives, pocket knives, folding knives, fixed blades and even serrated knives. The ceramic rod on the back specifically addresses serrated edges. Blade lengths from small paring knives to large chef's knives up to 25cm work with the system. The magnetic small knife holder accommodates thin blades that won't fit in the standard clamp.
The digital display shows angles in quarter-degree increments, providing professional-level precision. This accuracy level matches what commercial sharpening services use. The magnetic sensor attaches directly to the sharpening arm, so readings reflect the actual grinding angle rather than an approximation. Quarter-degree precision matters because small angle changes significantly affect cutting performance.
The heavy base provides sufficient stability for most sharpening tasks without mounting. However, mounting through the four holes gives maximum stability for heavy use or when sharpening large knives. The base weighs 810g, which prevents movement during normal sharpening. Mounting becomes more important if you're processing many knives or working with particularly dull blades that require more pressure.
A typical kitchen knife takes 10-15 minutes working through the grit progression from 220 to 800, plus ceramic and leather finishing. Very dull knives may require longer on coarse grits. The key is working systematically through each grit level until you achieve consistent scratches before moving to the next finer grit. Rushing between grits actually takes longer overall.
The complete kit includes the base plate, tilting main body, rubberised blade clamp, magnetic small knife holder, retaining block, sanding plate holder, six diamond plates (220, 320, 400, 600, 800 grit), one ceramic plate, one leather strop, digital angle guide and ceramic rod for serrated blades. Everything needed for professional results comes in the box.
Yes, the guided system eliminates the skill requirements of freehand sharpening. The angle guide ensures consistent bevels, the magnetic plates make grit changes simple and the stable base prevents common beginner mistakes. Following the included instructions and working through the grit progression systematically produces professional results regardless of experience level.
Move to the next finer grit when you see consistent scratch patterns across the entire bevel from the current grit. Each grit should remove the scratches from the previous coarser grit. The edge should feel progressively sharper as you work through finer grits. Skipping this step or rushing between grits results in uneven edges that won't hold sharpness.
Clean the diamond plates with water and a brush after use to prevent metal filings from clogging the abrasive surface. The ceramic plate needs occasional cleaning with a diamond plate cleaner. Wipe down metal components to prevent rust. The magnetic holders and digital display require no special maintenance. Proper cleaning extends plate life and maintains sharpening effectiveness.
