Component Breakdown
  • Turning mechanism: Allows only 0.1° of arm deflection at a force of 30N. Ability to fully lock the flip will be useful during the reprofiling of the knife when it is subjected to heavy loads and vibrations, as well as when sharpening particularly long blades, when additional protection against accidental flipping is needed.
  • Three-stage angle adjustment:
    - rough adjustment (accuracy up to 1°) with an extendable slider;
    - fine adjustment (up to 0.1°) with a rack and pinion mechanism;
    - ultra-fine adjustment (up to 0.01°) with the micro-adjustment unit.
  • The arrangement of the sharpening system parts allows you to set the sharpening angle in the range from 9° to 39.5° per side, for knives up to 430 mm in length.
  • Thickness compensator: Height adjuster is equipped with a removable stone thickness compensator. It provides a quick adjustment of the angle during stone change.
  • Abrasive holder: Provides increased mounting security and ensures immobility of the elements during operation. Instead of point locking with a screw, the mechanism now uses surface locking through cylindrical sleeves with holes. This reduces the force required to secure the elements and eliminates the possibility of the rod surface damage.
  • Rod parking: K4 carries over the stroke limiter and L-shaped piece from the K03, while introducing an upgraded parking system.
  • New detachable Axicube Shift: Axicube Shift sits on the far abrasive stop. It can be quickly and easily removed to reduce abrasive weight during sharpening and for easy charging away from the sharpening system. The new mounting, featuring a special rail in combination with a locking screw and a magnet, provides an easy and secure attachment of the angle finder for accurate measurement of the sharpening angle. Axicube-i can be charged via USB Type-C cable.
  • Quick clamps: Can securely hold knives up to 7 mm thick. They provide a fast and tool-free usage and a 300 N clamping force. Designed with finite element analysis, the clamps' structure evenly distributes stress for uniform jaw closure.
  • Removable clamping arm: The new removable design of the clamping arm will become your favorite feature of the K4. No need to take the knife out of the clamps or try and repeat its position and set the same sharpening angle anymore.
  • Rigid body and stable base: It attaches to the milled base with three rigid quick-release screws. Thanks to its shape, weight, and wide, slim shock absorbers, the system remains stable during sharpening.

Nice to know you have full protection
After a sever thunderstorm took out my cable modem, It was nice to be assured I had replacement coverage for it. Filing the claim was effortless and the process to return the item was no issue at all. My only concern is that the cable modem is a CRITICAL piece of equipment for any individual or business. A sense of urgency on the behalf of Asurion to recognize this and expedite the replacement process would have been appreciated. No technician repairs these modems. Always cheaper to replace, especially one that the failure was attributed to an electrical storm.

Asurion is a good investment
Bought an expensive gaming router 46 months ago. Just stopped working, had 2 months left on my insurance, they couldn't fix it and gave me a refund. Bought a similar router with another 4 years if insurance with Asurion and I couldn't be happier. All this in 1 weeks time. They are great

Surprisingly great service!
Surprisingly great service. I just didn’t expect my claim to be handled so efficiently. Replaced the purchase price of my printer that was 3 years into a 4 year protection plan.

Works, but reimbursement for damaged items come via Amazon Gift Card, not Cash
Just confirming that this protection plan actually works. Asurion first told me that they'd try and repair my item. Likely, they couldn't find someone to repair the type of item I bought (KVM), so they offered payment (original cost of the item) via Amazon Gift Card. Giving 4 out of 5 stars -> 4 instead of 5 because Amazon Gift Card isn't Cash. Cash is always better.
