Usage remarks

  • Be careful! All of the knives are really sharp!
  • The knife is designed for cutting, don’t use it as a crowbar or a dart.
  • Please remember, that the knife needs to be kept sharp at all times. Only then can it be used for its purposes.
  • The knife shouldn’t be washed in a dishwasher. It can result in it being damaged or destroyed.
  • Before putting your knife into the scabbard, please make sure that it is fully dry.
  • Preserve the knife’s blade regularly, with the help of the special PRUCIAK PROTECTOR
  • In case of folding knife, unless necessary, do not disassemble the knife !!!
  • The knife has open type bearings. If dirt gets in, you can wash it off with hot water, dry it with compressed air and apply a small amount of oil from the outside

  • We use PRUCIAK PROTECTOR GLIDE OIL FOR HERMAN KNIVES for lubrication

  • Wipe off any excess oil and the knife is ready for use

  • As the knives are used, a completely natural phenomenon of changing color of the linings can be observed. Anodized titanium has the property that it darkens upon contact with grease, and to restore its original appearance and shine, the knife must be thoroughly degreased. The situation is different with DLC and PVD coatings, which we recommend lubricating with Herman Glide oil, rubbing a small amount of oil into the entire knife, and then wiping the knife dry.

  • It is strictly prohibited to perform an impact test on the knife lock, consisting of striking the spine of an open knife against a hard object, or attempting to forcibly close the knife with the lock engaged. Such actions cause irreversible damage to the lock, which will void the manufacturer’s warranty.

  • Modifying the products results in the loss of warranty, which gives the manufacturer the right to refuse service, even for an additional fee

  • As of March 2025, Herman Knives has introduced new bearing washers made of M390 steel, giving the knives even smoother action and increased resistance to washer cracking. During the transitional period, sintered carbide washers were used, which are extremely hard. Combined with a new type of pivot featuring a finer thread pitch, the bearings now offer outstanding smoothness of operation thanks to the ability to make highly precise pivot adjustments.

    When tightening the pivot, care must be taken not to apply excessive force. The finer thread pitch allows for more precise adjustment, but this comes with a trade-off: it significantly increases the pressure on the ceramic balls and sintered carbide washers, which in turn raises the risk of ceramic ball cracking if the pivot is overtightened. All bearing components are manufactured with very high precision and extremely tight tolerances.

     

    Please be careful to tighten the pivot only to the point where blade play stops, and no tighter, as this can result in cracking of the ceramic balls or the sintered carbide washer.

    We have had several instances where people improperly tightened the pivot too much in the new Herman bearing system, causing the bearing balls to crack. The new Herman Torx T20 screwdriver, which is quite hefty and encourages users to experiment with knife adjustments, likely contributes to this issue. By the way, this screwdriver was designed from the ground up by Bartosz Herman and is manufactured in-house at Herman Knives.
