Blacksmithing requires a knowing how to move the metal to achieve a desired result. You can drawl the metal, twist it, punch it and upset it to name a few. The pictures below shows a German pattern (top) and a Swedish pattern (bottom) Which one moves metal faster? Examine the photo. Both hammers weigh 1500 gm. or 3.3 lbs. Assuming the same force is used the Swedish hammer will move the metal faster. It has a small radius on the face the surface area is smaller. But the German hammer will also move the same amount. What's that you say? You've heard the saying in physics "for every action there is an equal reaction". it applies here also. The smaller hammer moved a small area further than the German hammer but the German hammer moved more material, only less. If we measured it in molecules the same amount of molecules moved the same distance. How to apply the results come from hitting hot metal a lot and learning how it reacts to the hammers blow. Also notice the necks of the from the center of the handle to the face of the hammer. The distance The German hammer is shorter. continue below image Imagine a X-axis up through the handle. We'll call that the handle axis radius. In your hand that handle axis can rotate left or right. From the center of the axis to the face of the hammer. Let's call this the effective handle axis radius. Which is different than the radius of the hammer face radius itself. Just know there are two ideas here. When using the German short pattern hammer and bringing down the hammer it twist a few degrees the hammers handle axis radius will be less off the bulls eye target of where you want the blow to land. Because of the shorter distance from the handle radius to the hammers face than if you used the Swedish pattern hammer instead. The example above shows two hammers each with a different handle axis radius. The German short pattern will have less of the off target movement than the Swedish pattern hammer that has a larger handle axis radius.Below are some more examples of hammer types Above left to right. Craftsman 3lbs sledge hammer, Picard German 3.3 lbs. short pattern, Picard Swedish 2.2 lbs. hammer, French pattern .75 lbs. hammer and a Diamond rounding hammer.Below you can compare the hammers faces in the photos to the broad round face of the German short pattern. The smaller French pattern hammer has turned out to be an excellent hammer for me as I smooth out rougher forge marks because of it's flatter rectangular face. Each hammer has it pros and cons on how it's used and the jobs it is best for in the hand of a blacksmith. Add to that the hammer blows can be more to the toe or heel or left or right edges, creating different results. As a blacksmith you may want to dress your hammer face so it is more universal as well.Picard hammers are forged c45 steel with tempered faces and peens.
