Forge Ahead with Tool Steel: Selection and Use Tips for Modern Blacksmithing

Tool Steel Selection and Use in Modern Blacksmithing

Tool steel is an essential material for any blacksmith. It is the backbone of most tools used in the trade, from hammers and chisels to tongs and punches. Tool steels are defined by their high carbon content, which makes them hard and durable while still being workable with heat treatment. In this post, we will discuss the selection and use of tool steel in modern blacksmithing.

Selection of Tool Steel
When selecting a tool steel, there are several factors to consider. The first consideration should be the type of tool you intend to make or repair. Different types of tool steels have unique properties that make them suitable for specific applications.

The second consideration should be the desired hardness level of your finished product. Hardness is measured on a scale called Rockwell hardness (HRC). The higher the HRC number, the harder and more brittle the material becomes.

Lastly, it’s important to consider cost as some types of tool steels can be quite expensive compared to others.

Types of Tool Steel
There are many types of tool steel available on today’s market; however, not all are ideal for blacksmithing purposes. Some common options include:

– W1 Water-Hardening: This type of steel has low resistance to impact but holds an edge well.
– O1 Oil-Hardening: O1 offers excellent wear resistance & toughness making it useful for knives & other cutting tools.
– A2 Air-Hardening: This type shows better wear-resistance than other options due to its high chromium content.
– D2 High-Carbon: D2 offers excellent abrasion resistance & durability making it perfect for blades that require heavy-duty usage.

Use Of Tool Steels
Once you’ve selected your desired material(s), using proper forging techniques will help ensure optimal outcomes when crafting your tools or blades.

When working with raw steel, heat it in a forge to the desired temperature for forging. Once at temperature, use hammer blows and other tools such as tongs or anvils to shape the metal.

After shaping is complete, it’s time for heat treatment. Heat treatment involves heating your tool steel to a specific temperature and then quenching (rapidly cooling) it in water or oil. This process helps create the desired level of hardness needed for your finished product.

When making cutting tools like knives or chisels, be sure to cool them slowly after hardening by tempering them in an oven set at around 350°F. This process will reduce brittleness while also maintaining toughness.

Conclusion
Tool steels are essential materials when working with blacksmithing projects requiring hammers, punches, chisels & more. It’s crucial that you select the right type of tool steel based on the intended usage and desired hardness level of your final product(s). Proper forging techniques combined with careful attention to heat treatment can help ensure optimal outcomes when crafting tools from these materials.
