Performance Benefits
Explosive Power: Ideal for high-impact tire slams and overhead swings, developing explosive power in the core, shoulders, and posterior chain.
Rotational Strength: The long handle creates significant leverage, making it an elite tool for rotational exercises that translate to improved performance in sports like golf, baseball, and MMA.
Customizable Intensity: The loadable head allows athletes to scale the weight as they progress, moving from a standard 14 LB "speed" hammer to a 28 LB "power" implement.
Grip Endurance: The powder-coated steel handle requires consistent grip engagement during ballistic movements, significantly improving forearm and hand strength.
Maintenance and Care
Filling Instructions: To adjust the weight, remove the screws on the back plate of the head. Fill with dry sand or lead shot to your desired weight, then re-attach the plate securely.
Striking Surfaces: For the longevity of the hammer and the safety of the user, strike only specialized training tires or high-density rubber mats. DO NOT use on concrete, rocks, or metal surfaces, as this can damage the steel and cause dangerous recoil.
Cleaning: Wipe the powder coat with a damp cloth and mild soap to remove sweat and chalk. Dry immediately.
Rust Prevention: If the powder coat is scratched or the hammer is used in high-humidity areas, apply a light coat of 3-in-1 oil or WD-40 to any exposed steel.
Inspection: Periodically check the back plate screws to ensure they remain tight after repeated impact sessions. Inspect the welds for any signs of fatigue.
Warranty Information
The Rogue SISU War Hammer is warrantied against manufacturing defects in materials and workmanship.
Note: The warranty does not cover cosmetic damage to the powder coat from striking tires. Use on non-recommended surfaces (like concrete or rocks) will void the warranty.
Frequently Asked Questions
Q: How do I make it reach the maximum weight of 28 LB? A: To reach the 28 LB maximum, you must fill the head with lead shot. Using play sand will typically bring the total weight to approximately 20–22 LB.
Q: Can I use this for sledgehammer swings if I don't have a tire? A: It is highly recommended to use a tire. Striking a hard floor—even with mats—without the "give" of a tire creates significant vibration and recoil that can be hard on the joints and the hammer.
Q: Is the handle knurled? A: No, the handle features a textured black powder coat. This provides a secure grip while allowing for the slight hand rotation necessary during dynamic sledgehammer swings.
Q: Is it okay if the plastic end cap on the handle pops off? A: The end cap is a cosmetic closure for the tube. If it is damaged or lost during use, it does not affect the structural integrity or performance of the hammer.
