Its price buys a complete seven-abrasive progression, rotating V-block clamp, 1° angle adjustment, strop, case and three-year warranty. It is less permanent than all-metal systems, but its speed, completeness and edge quality per dollar are unusually honest; replacement abrasives are sold rather than forcing disposal of the tool.
Five grits cover repair through refinement and cut modern hard steels quickly.
Refines the scratch pattern before stropping.
Removes residual burr and improves cut feel.
Keeps weight and price down, though it is less rigid than KME or Hapstone.
Clear labels, quick three-sided abrasive carriers, easy angle dial and an organized case make the workflow excellent. Polymer flex and clamp movement on long or heavy blades are the principal ergonomic compromises.
Good: replaceable abrasive modules and a three-year warranty; expect less lifetime rigidity than KME or Hapstone because critical structure uses polymer.
