This wheel has exchangeable leather discs so you can easily replace a disc with a worn tip. Discs with alternative, narrower profiles are available as optional extra.
The two standard discs have a radius of 3mm (1/8") and a 60º tip. The set of optional extra discs (LA124) have a radius of 2mm (3/32") and a 45º tip. These smaller disc profiles permit the honing of small carving tools with very narrow profiles.
The diameter of the larger wheel has been increased from 100mm (4") to 120mm (4¾"), which speeds up the honing process.
This design has a larger and also deeper space between the two profiles, compared to the previous LA100, and therefore it permits inside honing of tools with wide and deep profiles.
You can also mount double LA120 wheels, one with standard profiles and one with set of narrow discs, and thus have access to four varying profiles at the same time.
