Anvil Anatomy: Getting the Most From The Horn, Face, and Edges
The anvil is more than just a block of steel to hammer on — it’s the blacksmith’s most versatile tool. Every curve, edge, and surface has a purpose, and learning to use each part effectively can transform your work from clumsy to precise.
In this post, we’ll break down the geometry of a typical anvil and explore how the horn, face, and edges can help you forge more efficiently and with greater control.
The Horn: Curves, Bends, and Transitions
The horn (the cone-shaped end of the anvil) is primarily used for bending and shaping curves.
Bending stock: The horn allows you to create smooth arcs and circles, whether you’re forging hooks, scrolls, or decorative elements.
Tapering: By rotating your work on the horn, you can draw out tapers into round or conical shapes.
Blending transitions: It’s useful for smoothing the junctions between straight and curved sections.
Tip: Use lighter hammer blows on the horn — too much force can cause dents or mar the smooth surface of your work.
The Face: Flat Work and General Forging
The face is the flat top surface of the anvil, and it’s the go-to area for most forging tasks.
Flattening stock: The wide, flat surface makes it perfect for smoothing and evening out material.
Drawing out steel: Repeated hammering across the face lets you lengthen and thin stock efficiently.
Planishing: Light, controlled hammer blows on the face can refine the finish of your work.
Tip: Keep your hammer face clean and your strikes accurate — the face of the anvil will reflect every blow onto your metal.
The Edges: Precision and Angles
The edges of the anvil are where you can create crisp transitions and bends.
Forging shoulders: Placing your work over the edge and hammering down creates defined shoulders, common in tools and joinery.
Controlled bending: The edge gives you a sharper angle than the horn, ideal for right-angled bends.
Texturing: Some smiths use edges deliberately to create decorative marks and textures.
Tip: Many anvils have slightly radiused (rounded) edges. Choose a sharper edge for clean corners, or a softer one for gentler transitions to avoid cracks.
Putting It All Together
A skilled smith moves fluidly around the anvil, using each surface as part of the forging process:
Start on the horn to rough in curves.
Move to the face for flattening and refining.
Finish at the edges to sharpen transitions or add details.
Think of the anvil as a toolkit built into one shape — it’s about learning to match the right geometry to the task at hand.
Final Thoughts
Mastering the geometry of your anvil isn’t just about efficiency — it’s about craftsmanship. Using the horn, face, and edges effectively allows you to control the flow of metal with precision and confidence.
