Jewelry Tools 101: Ultimate Guide to Jewelry Hammers
So back to the spiculum forming hammer … I looked for it in our jewelry-making tool eBook and found more kinds of hammers than I ever imagined. Naturally, I had to share.
The Illustrated Guide to Jewelry-Making Tools: Jewelry Hammers
By Sharon Elaine Thompson
Hammers are the most basic of the metalsmith's tools. Without a jeweler’s hammer, you are not a smith. Most hammers have two faces that are differently sized or shaped; mallets have identical faces. Most hammers have straight shafts; the exception is the chasing hammer. Most hammers can be used for several functions; some are specialized. The fundamental differences are this: there are hammers for striking metal and hammers for striking tools. A brief description of their uses follows. (Note: Peen refers to the business face of the hammer. A ball-peen is a ball-shaped face; a cross-peen is one that is at right angles to the handle.)
Raising hammer: two rectangular, blunt, or wedge-shaped cross-peen faces, used to "raise" the metal from flat sheet to dimensional form by striking the outside of the form.
Mallet: identical faces and can be made of plastic, rawhide, or metal.
Goldsmith's hammer: one flat and one cross-peen head for riveting and other work.
Forming hammer: a heavy hammer with flat or domed faces, used to move metal.
Planishing hammer: flat or convex faces, to smooth metal that has been worked by other hammers or to harden metal.
Ball-peen hammer: an all-purpose hammer with one round and one half-domed face, for flattening and shaping metal, removing dents; can be used to drive chisels, punches, stamps.
Chasing hammer: one flat face for striking other tools (such as stamps) or planishing metal; one round face for forming and riveting; handle has a bulbous end and a narrow neck for more bounce back and less strain on the wrist.
Riveting hammer: one round and one chisel-shaped face, for riveting, tacking, and lightweight forming.
Embossing hammer: two rounded, differently sized faces, for a variety of metalwork.
Texturing hammer: machined or patterned faces, for striking texture directly onto metalwork.

P.S. So what about that spiculum forming hammer? It's a very specialized tool used by jewelers to create spiculums … and apparently a spiculum is a long needle-like hollow form. The thin tips of a spiculum forming hammer are ideal for hammering a thin piece of metal into a grooved forming block.
