What etching and engraving mean on leather
Leathercraft has no fixed meaning for “etching” or “engraving.” In practice, both usually mean fine line work: cutting, pressing, gouging, burning or rotary carving that puts a line into the surface without the depth of full tooling. You don’t need acids or chemicals.
Use vegetable-tanned leather. It holds cut, pressed and burned lines well. Chrome-tanned leather does not hold pressed lines, and it can release toxic fumes when heated.
Line etching with a swivel knife
Line etching uses a swivel knife with little or no beveling, which gives a fine, engraved look. Cut on cased leather at the right moisture, using the same grip you would use for carving. For more on holding the knife, see how to hold and cut with a swivel knife.
Keep cuts to about a third to a half of the leather’s thickness. Deeper cuts don’t look better. They weaken the leather.
Modeling with a stylus on cased leather
On cased leather, a stylus or modeling tool presses lines in without cutting. The result is a soft, impressed line that suits lettering and simple outlines. Case the leather evenly: wet it, then wait until the surface color nearly returns to natural before you start.
Gouging for a narrow channel
A V-gouge or U-gouge removes a narrow channel. It works on dry or lightly damp leather. Adjustable gouges and groovers let you set the depth, and cuts should stay under about half the leather’s thickness.
Rotary tools and pyrography
- Rotary tool (such as a Dremel) with a small engraving bit works best on dry leather at low to medium speed. Use light pressure. On wet leather, the bit tears fibers rather than cutting cleanly.
- Pyrography (a wood-burning pen) can mark vegetable-tanned leather, but leather scorches faster than wood. Use low heat. Exact temperatures vary by pen, so test on scrap first.
Pyrography is not laser engraving. Heat control is much less precise, so the marks are less consistent. Wear eye protection with rotary tools.
Transferring the design
The most reliable method is to tape tracing film over the cased leather and trace the design with a stylus. Cased leather takes the impression cleanly, and the film can be reused.
You can mark dry leather with a pencil for a rough layout. Pencil marks can be hard to remove, so test on a scrap piece first.
Finishing the etched lines
Darken the lines with antique or dye, then wipe the surface so the lines stand out. Seal the piece with a top coat, such as Resolene or Tan-Kote, to protect the work.
Safety
- Burning leather produces smoke. Work with good ventilation.
- Never burn or heat chrome-tanned or faux leather. It can release toxic fumes.
- Wear eye protection when using rotary tools.
Hand work or a laser?
Hand etching is slower, but it gives a tactile, hand-made look. A laser is faster for repeat logos and fine text, but it produces a flat, burned image. If you are considering a machine, see whether a laser engraver can be used on leather and what laser is best for leather.
If you want a stamped mark rather than a drawn one, see leatherworking maker’s mark. For the basic tool set, start with leather carving for beginners.
