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.
Quotes
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.

Sneak Peek: Venev OCB Bonded Diamonds
The OCB version of Venev Diamonds utilizes a brand-new yellow binder with no abrasive particles in the composition. OCB is available in extra-fine grits only and offers better scratch-free sharpening result.
Venev OCB Diamonds are available in F 1200 grit (2.5 um) only. F 800 grit (6 um) will be released in Q1. Dual-sided formats of OCB will be released at the same time.

I have the original Venev diamond stone 1200 grit. Do I need the OCB?
Legacy binder composition includes medium-hard particles up to 7 microns large. (It was necessary to stabilize diamond/binder matrix.) As result, when sharpening some steels the legacy F 1200 and F 2000 may not show noticeable progression after F 800. In this case, the new OCB diamonds will be the good upgrade.
-
Do I need to lap OCB diamonds?
We recommend lapping all Venev diamonds including OCB because flatness tolerance is the same as for legacy diamonds. However, it's not mandatory for OCB version because the surface is finer.
-
How about OCB F 2000 grit?
It will not be released due to substantial technology limits. F 2000 will be legacy only.
