It all starts with a knife. A knife that deserves respect and requires proper maintenance. Keep it sharp, the magazine articles say. But this can be a difficult and frustrating process. Old crafts are becoming less important, and tool sharpening skills are no exception. Our mission is to ensure this craftsmanship endures. The idea of knife sharpening being performed by the individual to whom the knife belongs is close to our heart. As such, the support we offer our customers includes information about sharpening stones, abrasives and knife maintenance. We provide modern, high-quality sharpeners that give a fast, long-lasting edge, as well as various stones and accessories. We have a great love for the craft of knife sharpening, and our aim is to share this passion with our customers.

Linear Ball-Bearing Pivot Unit for Hapstone M2


$33.00 USD

The Linear Ball-Bearing Pivot Unit is an optional upgrade for the first revision of Hapstone M2 utilizing PTFE insert. The linear ball-bearing provides extra smooth shaft movement and requires no lubrication or cleaning.

One of the best selling points of flagship Hapstone R1 comes to Hapstone M2. The second revision of Hapstone M2 implements the linear ball-bearing pivot unit. Owners of Revision 1 can purchase the linear ball-bearing pivot unit separately.


The linear bearing equipped instrument, is by far the smoothest, and virtually play-free, guided rod system I've used thus far. There is no vibration, or perceivable movement, but its able to simultaneously exhibit extremely precise and smooth reciprocating, linear action.
