Notice for U.S. Customers

Dear Customers,

Due to circumstances beyond our control, including government decisions and new customs requirements, courier companies we work with have temporarily suspended shipments from Poland to the United States. In practice, this means:

  • carriers are currently refusing to accept parcels destined for the U.S.,

  • any packages that are sent may be subject to significant delays or returns,

  • additional customs procedures are further complicating the delivery process.

As a result, we are currently unable to fulfill orders to the United States.

If you are located in the U.S., we kindly ask that you refrain from placing orders until regular shipping options are restored.

We apologize for the inconvenience — this situation is beyond our control. We remain in contact with our shipping partners and are working to resume deliveries to the U.S. as soon as possible.

Reason for the Temporary Suspension of Shipments to the U.S.

As of August 25, 2025, new customs regulations in the United States have eliminated the previous duty exemption for goods valued up to $800. This means that every package containing goods may now be subject to additional duties and inspections.

The lack of clear procedures for duty collection and coordination with U.S. customs authorities has resulted in logistical chaos, preventing the efficient handling of parcels containing goods.

As a result, the dispatch of goods-containing shipments to the U.S. has been temporarily suspended — this applies to both parcels and declared-value letters. Only correspondence and documents can still be sent.

This is a temporary measure. We are closely monitoring the situation and will resume full shipping services to the U.S. as soon as logistics and customs conditions allow.

Kubey - one of the largest manufacturers producing knives of excellent quality at a great price! The motto of the company is "An Edge Above the Rest" / "Blade above all". With the use of high-speed CNC machine tools, milling machines, laser cutting or custom hand finishing, the brand focuses on quality workmanship and innovative approaches to design.

AUS-10 - Japanese stainless steel, often compared to 440C series steel, and for good reason, as the compositions are similar, but these minor differences make AUS-10 harder (hardened usually to around 60 HRC) and dulls more slowly, without losing its rust resistance. Knives made of this steel are relatively inexpensive and will be a great choice if our budget is not too high and we care about stainless.

Blade - drop point type, finished masking scratches and preventing glare with Stonewashed method and then coated with black coating. The long cutting edge, with a prominent belly, converges toward the needle-sharp tip of the wide blade. The thickness of the blade provides high strength while the high, flat grind gives excellent cutting edge geometry and extreme cutting performance. Ball bearing ceramic bearings are responsible for the smooth and smooth operation of the mechanism and support the opening of the blade with a fast front flipper (index-finger front flipper), we can also open the knife with a double-sided peg in the wedge (Thumb Stud). On the back of the upper jimping wedge, a notched thumb rest. Liner-Lock mechanism.

ULTEM™ - a plastic belonging to the family of Polyethermoids or simply PEI. This material is characterized primarily by high mechanical and impact strength with a very high strength-to-weight ratio. It is also characterized by high thermal resistance (180⁰C) and high chemical resistance to all kinds of solvents (synthetic and natural), lubricants or other chemicals. Adding to this total insensitivity to weather conditions, we get an ideal material for knife handles.

Handle - grips made of transparent Ultem™ plastic, textured to improve grip confidence, are bolted to the knife's steel frame. The so-called open-backed design without the typical backspacer, fastened together with steel spacer sleeves for easy cleaning. The simple, sturdy construction gives assurance of many years of use. Pivot decorated with stylized manufacturer's logo. Two-position (right/left) steel deep carry clip allows you to carry the knife discreetly in your pocket in tip-up position (blade tip up). Above the clip a lanyard hole, a hole for threading a safety or decorative cord.
