FAQs

• Is the RKS easy for beginners to use?
  Yes, the Work Sharp RKS was designed with first-time sharpeners in mind. Its guided design and rolling motion make it simple to achieve a consistent edge without any prior sharpening experience.
  
  
• Is it time-consuming to use?
  For honing or touch-ups, the Work Sharp Rolling Knife Sharpener works in just a minute or two. As a manual system, it is slower than powered ones when sharpening very dull blades, but it gets the job done within several minutes.
  
  
• Do I need to buy any add-ons to get the best performance?
  No, the Work Sharp Rolling Knife Sharpener comes with everything you need for effective sharpening right out of the box.
  
  
• Can I use replacement discs or accessories from other Work Sharp systems?
  Because the RKS is the only Work Sharp model that uses round sharpening discs, it is not compatible with replacement parts from other systems. Replacement discs are available from Work Sharp.
