Blacksmith Square Circle Rounding Hammer

• Precision in Every Strike: this hand-forged hammer is crafted for blacksmiths, bladesmiths, and metal artisans who demand perfect balance and control. At 11.81" (300mm) in length, it delivers exceptional precision in tight spaces – ideal for controlled blows, detailed forging, and fine adjustments at the anvil.
• Built to Last: the hammer head is forged from durable AISI 1045 steel, then hardened and tempered to achieve a Rockwell hardness of ~52-56 HRC. Fixed securely with a steel wedge, it’s engineered for stability and endurance through years of heavy use.
• Natural Feel: made from plain oiled ash wood, the handle provides a warm, secure grip and excellent shock absorption. Its ergonomic design ensures comfort and reduces fatigue during long forging sessions.
• Compact Powerhouse: weighing 1.09kg (2.4lbs), this hammer combines the strength of a full-sized tool with the agility of a compact design – making it a reliable choice for both workshop precision and professional blacksmithing performance.

HOW WE DO

Hardening:
We preheat the hammer to about 1200°F (649°C). Then we increase the temperature to 1450°F to 1500°F (788°C to 816°C). Quench the hammer in the water.
Tempering:
To reduce the brittleness and increase toughness, tempering is essential. We clean the surface of the hammer to expose bare metal. This helps in monitoring the tempering colours. We heat the hammer in an oven. Aim for a temperature between 400°F to 500°F (trying to get 225°C) for a good balance of hardness and toughness. We hold the temperature for at least an hour per inch of thickness. Then we allow the hammer to cool to room temperature.
Testing and Verification:
After tempering, we test the hammer's hardness using a Rockwell hardness tester. Also, we have a simple rebound test. we strike the hammer against an anvil; it should rebound without chipping or deforming.
