What is a Planishing Hammer?

Blacksmithing is an age-old craft that involves shaping and forming metal through heating and hammering. One of the essential tools in a blacksmith’s toolkit is the planishing hammer. A planishing hammer is a specialized tool used to smooth out surface imperfections, remove dents, and create an even finish on metal objects. In this article, we will take a deep dive into the world of planishing hammers, exploring their design, use, and benefits in blacksmithing.

Design of Planishing Hammers

Planishing hammers are typically made of metal and have two faces – one flat and one rounded. The flat face is used to smooth out metal surfaces and remove dents, while the rounded face is used to create curves and shapes. The hammer’s handle is usually made of wood, plastic, or rubber and is designed to reduce shock and provide a comfortable grip.

Planishing hammers come in a range of sizes, with different face diameters and handle lengths. The size of the hammer is chosen based on the type of metal being worked on, the thickness of the metal, and the size of the blacksmith’s hand. Smaller hammers are used for delicate work, while larger hammers are used for more heavy-duty tasks.

Uses of Planishing Hammers

Planishing hammers are primarily used to create a smooth and even surface finish on metal objects. This process is called planishing, and it involves hammering the metal until all dents, bumps, and other imperfections are removed. The result is a smooth, polished surface that is ready for painting, polishing, or any other desired finish.

Planishing hammers are used in a wide range of blacksmithing applications, including:

Smoothing out surface imperfections

Planishing hammers are used to remove dents, bumps, and other imperfections from metal surfaces. This process results in a smooth and even surface that is ready for final finishing.

Shaping metal objects

Planishing hammers can also be used to shape metal objects, creating curves and other desired shapes. The rounded face of the hammer is used to create these shapes, and the flat face is used to refine the shape and create a smooth surface finish.

Metal forming

Planishing hammers can be used to form metal into specific shapes, such as cones, cylinders, or other custom shapes. The metal is heated to make it malleable, and then the hammer is used to shape it into the desired form.

Repairs: Planishing hammers are also used to repair metal objects, such as car parts, metal furniture, or other metal objects. The hammer is used to remove dents, smooth out surfaces, and create a new, even surface finish.

Benefits of Planishing Hammers

There are several benefits to using planishing hammers in blacksmithing, including:

Ease of use

Planishing hammers are easy to use and require minimal training. Blacksmiths can quickly master the technique of using a planishing hammer and use it to create a range of metal objects with ease.


Planishing hammers are versatile tools that can be used in a wide range of blacksmithing applications. They can be used to shape metal, remove surface imperfections, and create a smooth surface finish.


Planishing hammers are made of metal, making them durable and long-lasting. They are designed to withstand the rigors of heavy-duty use, and with proper care, they can last for a long time

Reduced Physical Strain

Blacksmithing can be a physically demanding activity, but planishing hammers are designed to reduce the physical strain on blacksmiths. Their handles are typically made of materials that absorb shock and reduce vibration, reducing the risk of hand fatigue and injury. This increased comfort and reduced strain can allow blacksmiths to work for longer periods, improving their overall efficiency and productivity.

Increased Precision

Planishing hammers are designed to provide blacksmiths with increased precision and control when shaping and forming metal. The flat face of the hammer allows blacksmiths to remove dents and surface imperfections precisely, while the rounded face provides the necessary control to create curves and custom shapes. This precision and control can lead to improved results and more accurate finished products.


In conclusion, planishing hammers are essential tools in blacksmithing, providing numerous benefits that help blacksmiths to achieve their desired results quickly and efficiently. With their versatile design, increased speed and efficiency, reduced physical strain, and increased precision, planishing hammers are a valuable investment for any blacksmith.
