Hapstone K1 sharpener has a new compact design intended for mobility. It is positioned as a portable model minimized in size and it can be easily moved from one place to another. To provide this, the sharpener is equipped with folding legs and a collapsible horizontal shaft. The sharpener is very stable on any surface due to the extended base of support surface and rubber pads on the legs.

Sharpening stone holder is completely identical to M2 sharpener holder, has a spring clip and can hold stones up to 160 mm (6”) long, ensuring full compatibility with Edge Pro and KME format stones. Rotation mechanism in Hapstone K1 basic package is equipped with two clips for a knife made of duralumin.

Leather Strop is an efficient way of final polishing a cutting edge using Hapstone or Edge Pro knife sharpener. A leather strop enhances the cutting edge by correcting small nicks and smoothing grooves. The working surface is made of a very smooth high-quality cowhide leather mounted on a high-quality aluminum blank.

Leather strops are available in standard and narrow sizes. Narrow strops (12 mm wide) are suitable for recurved blades.

Gently slide the cutting edge over the strop, repeating 20-30 times for each side of the blade. The motion should avoid damaging the strop with the cutting edge.

Small Side Clamps for Hapstone R2 and Hapstone Rotating Module utilize CNC milled superelastic duralumin alloy jaws. Small clamps can be combined with other small clamps.

The kit includes 2 clamps. Small Side Clamps are part of Hapstone R2 Lite kit.

FAQ

• 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.
