  • Why new Hapstone sharpeners don't support 8" sharpening stones?
    I want to use my 8" bench stones. I will buy a sharpener with 8" stone support.
    Hapstone R2 is smaller than Hapstone R1. Does it mean R1 is better?
    Hapstone R2 is much cheaper than Hapstone R1. Does it mean R1 is better?
    How to use new clamps on Hapstone R1? Can I upgrade R1 to R2?

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

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

  • 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 available in 4 different kits in different price ranges. Hapstone R2 Classic is the successor of Hapstone R1: triple clamp configuration, fine-tuning adapter, and spring-assisted stoppers. Hapstone R2 Classic is cheaper than Hapstone R1, but the price difference is not big. At the same time, Hapstone R2 has a better stone holder and better clamps.

  • All new clamps and the new rotating clamp module are incompatible with Hapstone R1. The adapter is in development. Hapstone R1 owners will get it for free with the purchase of a new rotating clamp module.
