GearConnect is the family of clamp adapters to build "cross-platform" sharpening systems. An adapter connects the clamp bar of a host (Hapstone R2) to a clamp designed for another sharpening system. Adapters consist of 3D printed parts made of hard PLA plastic and steel bolts for maximum rigidity.

When multiple clamps are used together, it’s very important to have the same length. Clamps made by different manufacturers vary in length, but GearConnect solves the problem. GearConnect adapters extend attached clamps to one of two predefined lengths that we call "profiles".

• Hapstone R2 Standard Profile (long) = all clamps will have the length of long Hapstone clamps in R2 Standard, Classic, and BLACK. 
• Hapstone R2 Lite Profile (short) = all clamps will have the length of short Hapstone clamps in R2 Lite.

GearConnect Extension for Hapstone R2 Lite extends short Hapstone clamps to the length of long Hapstone clamps. Owners of Hapstone R2 Lite can buy any clamps and GearConnect-adapters for Hapstone R2 Standard. A pair of Extension adapters are required to use stock clamps and longer clamps at the same time.
