A graver — also known by its French-derived synonym burin — is a small, hand-held steel cutting tool used to remove fine shavings of metal by being pushed, under controlled hand pressure, across or into a metallic surface. It is the primary instrument of the hand engraver's craft and remains indispensable in jewellery making for tasks ranging from the incision of decorative lines and lettering to the raising of beads in pavé and bead-setting, the creation of bright-cut facets, and the undercutting of claws and collets. Despite the advent of pneumatic handpieces, laser engravers, and computer-aided milling, the hand-pushed graver retains a place at the bench wherever the finest control of surface texture and line quality is required.

Construction and Materials

A graver consists of two principal components: the steel shaft and the handle. The shaft is typically manufactured from high-carbon tool steel or, in more modern versions, high-speed steel (HSS) or tungsten carbide-tipped stock. High-carbon steel is easier to sharpen but loses its edge more quickly on hard alloys such as platinum; HSS and carbide variants hold an edge considerably longer and are preferred when working platinum or hardened white-gold alloys. The shaft is square, rectangular, or otherwise profiled in cross-section depending on the graver's intended type, and is cut to a working length of roughly 75–100 mm before being fitted into a handle.

The handle is traditionally a short, mushroom-shaped wooden piece — often boxwood or a dense hardwood — designed to rest in the palm of the hand so that the heel of the hand can apply forward pressure while the fingers guide direction. Some contemporary engravers favour ball-shaped or pistol-grip handles. The graver shaft is seated into the handle with a tight friction fit or secured with a ferrule, and the working end is ground and honed to a precise cutting geometry before use.

Profiles and Their Applications

The cross-sectional profile of the shaft determines the character of the cut the graver produces. The principal profiles in common use are as follows:

• Flat graver: A rectangular cross-section ground to a chisel-like cutting edge. Used for removing broad, shallow areas of metal, for bright-cutting (producing the high-polish, faceted cuts characteristic of Georgian and Victorian jewellery), and for cleaning up flat surfaces. The width of the cutting face can range from under 0.5 mm to several millimetres.
• Square graver: A square cross-section presented at 45 degrees so that one corner forms the cutting point. Produces a V-shaped groove and is widely used for line engraving, lettering, and decorative scrollwork. It is also employed to raise the small metal beads used in bead-setting.
• Lozenge (or diamond-point) graver: A rhomboid cross-section that produces a sharply defined V-groove with a distinctive profile. Particularly suited to fine-line decorative work and to cutting the precise, clean lines required in heraldic engraving and die-sinking.
• Onglette graver: A narrow, slightly curved profile derived from the French ongle (fingernail). The onglette is highly versatile, capable of producing both fine lines and broader sweeping cuts depending on the angle of presentation; it is a favourite for script lettering and for the flowing curves of taille-douce intaglio work.
• Knife graver: A thin, blade-like profile used for very fine detail work, for undercutting the edges of settings, and for trimming metal in confined spaces. Its narrow geometry allows access to areas inaccessible to wider tools.
• Bead (or round) graver: A rounded tip used specifically in stone-setting to push up and round off the small metal beads that secure stones in pavé, grain, and bead settings. Strictly speaking, the bead graver does not cut so much as burnish and form.
• Spit-stick (or chisel) graver: A broad, flat variant used for removing larger areas of metal or for inlay work.

Sharpening and Geometry

The performance of a graver depends entirely on the precision of its cutting geometry. The two critical angles are the face angle (the angle ground on the top face of the shaft, which determines how the tool presents to the work) and the heel angle (the small secondary bevel ground on the underside of the tip, which lifts the cutting edge clear of the work surface and controls depth of cut). A face angle that is too steep will cause the graver to dig in and chatter; one that is too shallow will cause it to skate across the surface without biting.

Sharpening is carried out on an oilstone (Arkansas stone being traditional) or, increasingly, on a diamond lap or ceramic honing plate. The graver is held at the correct angle against the abrasive surface and pushed forward in short, consistent strokes. Maintaining a flat, consistent face requires practice; many engravers use a small sharpening jig or fixture to hold the graver at a repeatable angle. After grinding on a coarser stone, the edge is refined on a fine stone and finished by stropping on leather charged with a fine abrasive compound. A correctly sharpened graver should cut cleanly and silently, producing a continuous, curling chip of metal rather than a rough, torn surface.

The frequency of resharpening depends on the metal being worked. Soft yellow gold and silver are relatively gentle on cutting edges; platinum, palladium, and work-hardened alloys dull a high-carbon steel graver rapidly, making HSS or carbide alternatives considerably more practical for production work.

Technique and Use at the Bench

The graver is held with the handle resting in the palm, the shaft lying between the thumb and the first two fingers, and the tip of the index finger or thumb of the same hand acting as a depth stop and pivot point against the work surface. Forward pressure is applied by the heel of the hand and the wrist, while direction is controlled by rotating the work — traditionally held in a pitch bowl, engraver's block, or ring clamp — rather than by steering the graver itself. This counter-intuitive technique, in which the work turns beneath a relatively fixed tool, is one of the defining skills of the trained hand engraver and takes considerable time to internalise.

In stone setting, the graver is used in a somewhat different manner: to raise beads from the surrounding metal, to cut bright-cut facets between stones, to undercut the walls of a collet or bezel so that metal can be pushed over a stone's girdle, and to clean up the surfaces around a completed setting. The setter's graver work is typically less about flowing decorative lines and more about precise, localised metal removal and forming.

Historical and Contemporary Context

The use of metal-cutting burins extends back to antiquity; engraved seals, coins, and intaglio gems from ancient Mesopotamia, Greece, and Rome were produced with tools functionally similar to the modern graver. The craft reached a high point of refinement in the European goldsmithing tradition of the fifteenth through eighteenth centuries, when engraved decoration — gravure en taille-douce, bright-cut work, and engine-turned grounds — was central to the aesthetics of fine jewellery and silver. The nineteenth century saw the development of standardised graver blanks produced by specialist tool manufacturers, making consistent geometry more accessible to the working jeweller.

In the contemporary workshop, hand gravers coexist with pneumatic engraving handpieces (such as the GRS AirGraver and the Foredom system), which use compressed air to deliver rapid, controlled impacts to the graver tip, reducing hand fatigue and allowing work on harder materials. Nevertheless, the hand-pushed graver remains the tool of choice for many engravers working on delicate or highly detailed pieces, and for stone setters performing finishing work where the sensitivity of direct hand contact is valued. The principles of geometry, sharpening, and technique are identical whether the graver is pushed by hand or driven pneumatically.
