If you already have a collection of sharpening stones, or if you plan to purchase stones of your choice, choose the Barebone kit with no stones.
We provides the 5-year warranty on Hapstone R2 knife sharpeners. You can be sure of the reliability of the devices and support from the manufacturer for the entire period of use.
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" Edge Pro. 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: 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.
How to use new clamps on Hapstone R1? Can I upgrade R1 to R2?
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.
