Why These Techniques Matter
Before you can forge a blade, a hook, or a hammer head, you need to move metal. In blacksmithing, drawing out and tapering are the two foundational operations that underpin almost every project you'll ever make. They look simple — and with practice, they become second nature — but poor technique leads to cold shuts, crooked stock, and wasted heats.
This guide breaks down each technique clearly, covering how to set up each blow, which part of the anvil to use, and how to read the metal as you work.
Understanding Drawing Out
Drawing out is the process of lengthening a piece of steel by reducing its cross-section. Imagine squeezing a lump of clay between your palms and rolling it thinner and longer — drawing out does the same thing, but with hammer and anvil.
How to Draw Out Effectively
- Heat the steel to a bright orange working temperature. Pale yellow is acceptable for mild steel but gives you less time to work.
- Work on the horn or the edge of the anvil face for aggressive drawing, or flat on the face for more controlled elongation.
- Use overlapping blows. Each hammer strike should overlap the previous one by roughly half. This distributes force evenly and prevents rippling.
- Rotate 90 degrees frequently. Strike a series of blows on one face, then rotate the bar and strike the adjacent face. This keeps the cross-section consistent and prevents the bar from dishing or curling.
- Finish on the flat of the anvil to straighten any bow introduced by the process.
Common Drawing-Out Mistakes
- Hammering too cold: Working below red heat introduces internal stress and can cause cracking.
- Inconsistent blow placement: Random strikes create uneven thickness along the bar.
- Neglecting rotation: Leads to a flat, ribbon-like cross-section instead of a consistent rectangle or round.
Understanding Tapering
Tapering is a specific form of drawing out where you intentionally reduce one end of the stock to a point, wedge, or cone. It's how you form knife tips, nail points, tenon ends, and any terminal detail that needs to narrow down.
How to Taper Correctly
- Start at the end of the bar and work back toward the body, not away from it. This moves material in the right direction.
- Use the anvil edge or far edge of the horn at roughly a 45° angle for fast material movement at the tip.
- Work two opposite faces first, creating a diamond cross-section at the tip, then address the remaining two faces to square it up — or leave the diamond if you want a four-sided point.
- Maintain consistent taper angle by checking visually after each heat. The transition from full stock to tip should be smooth and even.
Four-Sided vs. Two-Sided Tapers
| Taper Type | Best For | Technique |
|---|---|---|
| Four-sided (square) | Punches, drifts, chisels | Work all four faces equally |
| Two-sided (flat wedge) | Blades, wedges, leaves | Work only top and bottom faces |
| Round | Nails, rivets, pins | Rotate continuously while hammering |
Combining Both Techniques
In practice, most forge projects use drawing out and tapering together. A knife blade, for example, requires you to first draw out the bar to rough length, then taper the distal end for the tip, and potentially draw out the tang in the other direction. Learning to move fluidly between the two operations — reading the metal's color, adjusting angle on the fly — is what separates a developing smith from a skilled one.
Practice Drill
Take a piece of 1/2" mild steel square stock about 8" long. In a single session, draw it out to 12" in length, then taper one end to a round point and the other to a flat wedge. Compare both ends. This single exercise teaches you more about hammer control, heat management, and anvil positioning than any amount of reading can.
