  • Why new Hapstone sharpeners don't support 8" sharpening stones?

    Haptone has 8" stones support since the first version of Hapstone PRO. The best stone form-factor today is 6"  All new knife sharpeners must support it. 8" stones support is declared useless and economically unreasonable.    

  • I want to use my 8" bench stones. I will buy a sharpener with 8" stone support. 

    You will not use 8" bench stones even if your sharpener supports 8" stones. Bench stones are too heavy and obstruct visibility.

  • Hapstone R2 is smaller than Hapstone R1. Does it mean R1 is better?

    Hapstone R2 becomes smaller for one reason - 8" stone support has been eliminated. The main stone form factor is 6" Edge Pro. Hapstone R2 becomes 2" smaller and lighter.

  • Hapstone R2 is much cheaper than Hapstone R1. Does it mean R1 is better?

    Hapstone R2 is available in 4 different kits in different price ranges. Hapstone R2 Classic is the successor of Hapstone R1
