Performance hammers

Helpful information about performance hammers in a nutshell

1 Application and selection

Choosing the right athletic hammer depends on several key factors that directly affect performance and safety of use. Professional athletes, coaches and competition organizers should take into account such aspects as the level of the athlete, the specification of the equipment and the conditions in which the competition will take place.
Use in competitions and training
- Athletic hammers are a key component in both professional competitions and daily training. In the context of competitions, hammer selection must comply with World Athletics regulations, which strictly define equipment requirements. Only WA-certified hammers are used during international competitions, which guarantees their compliance with the standards and ensures fair competition conditions.
- For training, the choice of hammer can be more varied. Coaches often use hammers of different weights and diameters to match the intensity of training to the athlete's level. For example, lighter hammers are used to improve technique and swing speed, while heavier hammers help build strength and endurance.
In this case, it is worthwhile to learn more and see the separate range of training hammers for throwing ,which help focus more on training coordination, precision and throwing technique due to the lighter variants, or endurance and strength through the heavier variants. click the link
Criteria for choosing a hammer for an athlete
- Experience level: Beginner athletes can start with lighter hammers with weights such as 3 kg, 4 kg to gradually develop throwing technique and avoid injury. More experienced athletes can experiment with heavier hammers to improve their performance.
- Throwing style: throwing technique plays a key role in hammer selection. Athletes who prefer a dynamic, fast style may choose hammers with a smaller diameter, such as 95mm, which allows for faster spins and longer throws. In contrast, athletes focusing on control and precision may prefer hammers with a larger diameter of 110 mm or more.
- Training conditions: Depending on weather conditions, the material of the mallet may vary. In humid climates, stainless steel and brass are more resistant to corrosion, increasing durability and reliability. In dry conditions, steel coated with special coatings can be just as effective.
- Training Purpose: At different stages of preparation, hammers of different weights can serve different training purposes. In general, during the preparation period, heavier hammers can be used to increase strength, while lighter hammers are used in the pre-start period to improve dynamics and speed.
Technical specifications of hammers
- Each athletic hammer must meet certain standards and specifications, which are precisely defined by World Athletics. Among the most important parameters are:
Weight of the hammer: The most common weights are 4 kg, 5 kg, 6 kg and 7.26 kg, with the choice of the appropriate weight depending on the age category and gender of the athlete.
Head diameter: Depending on the model and material, the diameter of the hammer head can vary, usually between 95 mm and 127 mm. The right diameter affects aerodynamic properties and stability during flight.
Head material: steel, stainless steel, brass and composite materials are most commonly used for hammers.

2 Design and materials

Steel hammers
- Are one of the most popular choices among athletes due to their durability and affordability. The head of steel hammers is usually made of carbon steel, which has high hardness and excellent tensile strength. In order to prevent corrosion, these heads are usually coated with a protective layer, such as zinc electroplating, which not only protects against external influences, but also gives an aesthetic appearance. The process of turning steel heads ensures precise balance and optimal diameter, which is crucial for the stability of the hammer's flight. The head filling is a mixture of lead and steel shot, which allows the hammer to have a precise center of gravity. The hammer's cable, made of high-strength steel wires, is galvanized for durability and corrosion resistance. The hammer's handle is ergonomically designed to provide a firm grip and minimize hand fatigue during throwing.

Stainless steel hammers
- Stainless steel hammers are the preferred choice for athletes who need a tool with high corrosion resistance, which is crucial during heavy use in various weather conditions. The head of these hammers is made of polished stainless steel, which, thanks to its chromium content, forms a passive oxide layer to protect against corrosion. Polishing the head reduces drag, which improves the aerodynamics and trajectory of the hammer. Stainless steel, being an extremely durable material, is able to withstand repeated impacts and loads without losing its properties. The hammer cable is made of high-quality stainless steel and is also electro-galvanized, which increases its durability. The handles of stainless steel hammers are designed for maximum ergonomics, often featuring non-slip coatings or special embossing to ensure a firm grip and control during the throw.

Brass hammers
- Thanks to the unique properties of brass, these balls are chosen by athletes who value stable performance and exceptional durability. The heads of these hammers are made of brass - an alloy, copper and zinc, which has excellent corrosion resistance and the ability to absorb energy. Brass is also easy to machine, allowing the heads to be precisely turned and polished, ensuring perfect balance and optimal aerodynamics. The head filling, as in other hammers, consists of a mixture of lead and steel shot, allowing for precise center of gravity alignment. The lines in the brass hammers are made of high-strength, corrosion-protected steel, and the handles are ergonomically designed to provide maximum control and comfort when making a throw.

3. PREMIUM / Ziolkowski hammers

- These are unique tools that stand out from other hammers on the market, both in terms of craftsmanship and quality of workmanship, as well as the technology used in their manufacture. Created with top-class athletes in mind, these hammers are a symbol of excellence in the field of athletics, offering equipment that not only meets, but often exceeds the requirements set by international standards. They are the result of combining the latest technological advances with years of experience in the production of sports equipment. Every component of these hammers, from the head to the handle, is precisely designed and made of top-quality materials such as stainless steel, brass and special metal alloys. The heads of these hammers are carefully balanced for optimum trajectory and maximum throwing efficiency. The protective coatings used on the surfaces of the heads and the high quality of the filling guarantee not only excellent performance, but also the longevity of the equipment, even under intensive use.
- The Ziolkowski series hammers are also distinguished by their unique design, which was developed taking into account the comments and experience of Olympic champion Szymon Ziolkowski. His knowledge and practical approach to hammer throwing have contributed to the creation of hammers that are ideally suited to the needs of professional athletes. Each hammer in the series is not only a sports tool, but also a tribute to his successes and knowledge, making it unique in the eyes of athletes around the world. Working with POLANIK to design hammers bearing his name was a natural step in his career, allowing him to pass on his experience and knowledge.
