Bearing system: Custom-made ceramic ball bearings by Herman Knives

New improved bearing system.

Washers made of M390 powder metallurgy steel further enhance the already exceptional operation of our knives. Every stage of production has been optimized to ensure even greater precision, durability, and, most importantly, the smoothness of our knives.

Washer manufacturing process:

M390 steel is machined in-house on our Swiss-type lathe Citizen Cincom A20, where the bar stock is processed and pre-drilled.

Washer dimensions: Inner diameter 5.05 mm, outer diameter 11.95 mm; (for Bee and Micro Sting models: outer diameter 9.95 mm).

25 mm-long rods undergo vacuum heat treatment to 60 HRC, reducing material stress and minimizing the risk of deeper blade scratches and ceramic ball fractures.

After hardening, washers are machined using EDM (Electro Discharge Machining) on our Mitsubishi MV1200R wire EDM machine, allowing precise inner hole execution.

They are then wire-cut into 0.6 mm-thick slices, and final wire processing minimizes surface roughness.

Final manual lapping, up to a 4000-grit finish, gives the washers an almost mirror-like surface, ensuring even smoother bearing operation.

All these processes are carried out entirely in-house by Herman Knives.

New, improved pivot with DLC coating. We have refined the pivot construction, elevating its precision and the smoothness of the knife’s operation to an even higher level.
It consists of three elements:

A phosphor bronze bushing (a highly durable material with self-lubricating properties). It is precisely fitted to the hole in the blade, which is also machined in-house using our EDM machine. This eliminates all unnecessary play, ensuring flawless blade rotation through the resulting plain bearing.

A seven-petal clover-shaped screw – prevents rotation within the construction.

Torx T20 – secured with an easily removable Loctite for adjustability. If adjusting, be sure to reapply the same type of thread locker.

The screws are made of vacuum-hardened stainless steel. All three components are produced in-house by Herman Knives on our Swiss-type automatic lathe.

Bearings with increased stability

Based on years of experience, the new bearings feature a caged design with 16 ceramic balls. Their well-thought-out and tested structure effectively prevents ball displacement while ensuring optimal smoothness of operation.

Simple, isn’t it?
