Leather carving is the process of giving a three-dimensional appearance to leather craft objects or works of art by cutting and stamping the surface. Many different kinds of leathers can be used for these crafts.
The only type of leather suitable for carving is vegetable tanned, full grain leather.[ citation needed ] This is because the vegetable tanning process allows the leather to absorb water, which is used to soften the leather before the carving process, and the grain of the leather is necessary to allow the leather to hold the shape after the carving process is complete. Other leathers lack these two essential qualities. While the process of cutting into the leather and pushing the edges of the cuts in is relatively modern, marking wet leather has been around since the Roman period. There are some examples of Roman leather at Vindolanda near Hadrian's wall and the book "Purses in Pieces" is very informative with some lovely examples of medieval carved leather work. Historically, tools for stamping leather would probably have been made out of bone, but would not have been too different from those used today.
Three main tools are used in leather carving:
This tool, which creates an impression similar to that of a sea shell, is used to add emphasis to areas of a carving, often in the stem or down the centre of a leaf in a floral design. It is used in a similar way to other stamping tools, by holding it vertically over the leather and striking with the rawhide mallet. When using the Camouflage tool, the impressions created should be equally spaced, starting from the centre of the design and working out towards the tips of the stems or leaves in the design. The impressions should get progressively lighter.
The Pear shader is used to press down areas of the design that need to appear curved. The action of the pear shader causes the leather tooled by it to appear slightly darker. The pear shader is slightly unusual in that it may be tilted during use to provide the desired effect. It should be moved only slightly between each tap with the mallet so that it creates a consistent shading of the leather.
This tool is used to create an indention on one side of a cut so that one side is raised. This tool, when used correctly, can produce very realistic results. There are many variations of this tool that include a variety of shapes, such as diamonds or ovals. There are also a variety of faces that include striped, checked, rounded, smoothed, and crosshatched
These tools create a curved impression of a series of short, closely spaced lines. They may be used interchangeably, the only difference being that the veiner creates a simple curved line, while the shell tool has a pattern resembling the edge of a scallop along the inside edge. They are used to continue to create the impression of depth created by the beveler, and to create the impression of a curved surface. These tools are used in the usual way, but like the pear shader, may also be tilted to help create the impression of depth where they are used beside a cut.
The seeder creates a small circular impression, that is used to represent seeds. As the face of this tool is so small, care must be taken when striking that you do not cut right through the leather. If stamping an area using this tool, stamp around the outside first, then fill in the centre.
This step in producing a carved leather article is used to emphasise the design, and is not even necessary in some cases. It consists of the pushing down of any areas of leather that have not been already carved. The background tool has a crosshatched pattern on its head, which has the effect of significantly darkening the leather it is used on. As with the seeder, the face of this tool is often small, so care must be taken not to strike it too hard.
When using this tool, take care that the impressions created by it do not overlap, and also take care not to stamp into the design or over the border. When the entire face of the tool is not needed, or to create tidy corners, the tool can be tilted so only part of the face creates an impression.
All leather needs to be prepared a certain way for leather carvers to carve the leather. The leather carver will "case" the leather by soaking it in water, then letting it dry to the proper dampness, thus making the leather easier to tool. If the leather is too dry, impressions will fade over time, or will not be made to a consistent depth. Too wet, it will not hold a sharply defined carving. Properly cased leather feels cool to the touch, and has the feel, of firm, wet clay. A damp sponge can be used to maintain the dampness while tooling but should never be used to replace proper casing.
When the leather has been properly cased, the swivel knife is used to make the bold cuts that form the backbone of the carved image. These cuts are made to a depth of up to approximately half the thickness of the leather being used, depending on the effect desired by the leather worker. Care must be taken during this step to keep the swivel knife vertical at all times, as any tilt is detrimental to the ability of the leather to be properly stamped later in the carving process.
Veiners, Seeders, and other Specific Tooling
Various other tools may be needed to add details to the carving depending on the pattern. Here is where the carver can add character, especially to floral carving.
After shading is completed with the Pear Shader, the Beveler is used to compress one side of the cut. This creates the impression of depth by pressing down parts of the image relative to the foreground. The Beveler is used by holding it vertically, with the foot of the tool in contact with the leather, and striking it lightly with the rawhide mallet. The tool is then moved forward along the cut about half its width, and struck again with the mallet. This process is completed until the entire length of the cut has been appropriately beveled.
As a general rule, the outside of curves and the outside edge of anything overlapping another part of the design is beveled. The exception to this rule is leather that will later be stamped with another tool, and, if the background is to be treated with the background tool, the background itself.
This is the final step in creating a carved design. The swivel knife is again used to create small, decorative cuts in the design to enhance its appearance. These cuts may be made in parts of the design that have already been stamped, which is why it is necessary to leave this step until last.
A knife is a tool or weapon with a cutting edge or blade, usually attached to a handle or hilt. One of the earliest tools used by humanity, knives appeared at least 2.5 million years ago, as evidenced by the Oldowan tools. Originally made of wood, bone, and stone, over the centuries, in step with improvements in both metallurgy and manufacturing, knife blades have been made from copper, bronze, iron, steel, ceramic, and titanium. Most modern knives have either fixed or folding blades; blade patterns and styles vary by maker and country of origin.
Engraving is the practice of incising a design onto a hard, usually flat surface by cutting grooves into it with a burin. The result may be a decorated object in itself, as when silver, gold, steel, or glass are engraved, or may provide an intaglio printing plate, of copper or another metal, for printing images on paper as prints or illustrations; these images are also called "engravings". Engraving is one of the oldest and most important techniques in printmaking. Wood engraving is a form of relief printing and is not covered in this article, same with rock engravings like petroglyphs.
A chisel is a wedged hand tool with a characteristically shaped cutting edge on the end of its blade, for carving or cutting a hard material. The tool can be used by hand, struck with a mallet, or applied with mechanical power. The handle and blade of some types of chisel are made of metal or wood with a sharp edge in it.
The art of paper cutting in China may date back to the 2nd century CE, when paper was invented by Cai Lun, a court official of the Eastern Han dynasty.
Wood carving is a form of woodworking by means of a cutting tool (knife) in one hand or a chisel by two hands or with one hand on a chisel and one hand on a mallet, resulting in a wooden figure or figurine, or in the sculptural ornamentation of a wooden object. The phrase may also refer to the finished product, from individual sculptures to hand-worked mouldings composing part of a tracery.
Embossing and debossing are the processes of creating either raised or recessed relief images and designs in paper and other materials. An embossed pattern is raised against the background, while a debossed pattern is sunken into the surface of the material but might protrude somewhat on the reverse side.
A peeler is a kitchen tool, a distinct type of kitchen knife, consisting of a metal blade with a slot with a sharp edge attached to a handle, used to remove the outer layer of some vegetables such as potatoes, broccoli stalks, and carrots, and fruits such as apples and pears. A paring knife may also be used to peel vegetables. The blade of a peeler has a slot with one side sharpened; the other side of the slot prevents the blade from cutting too far into the vegetable.
Stone carving is an activity where pieces of rough natural stone are shaped by the controlled removal of stone. Owing to the permanence of the material, stone work has survived which was created during our prehistory or past time.
A drawknife is a traditional woodworking hand tool used to shape wood by removing shavings. It consists of a blade with a handle at each end. The blade is much longer than it is deep. It is pulled or "drawn" toward the user.
A miter saw or mitre saw is a saw used to make accurate crosscuts and miters in a workpiece by positioning a mounted blade onto a board. A miter saw in its earliest form was composed of a back saw in a miter box, but in modern implementation consists of a powered circular saw that can be positioned at a variety of angles and lowered onto a board positioned against a backstop called the fence.
A kitchen knife is any knife that is intended to be used in food preparation. While much of this work can be accomplished with a few general-purpose knives – notably a large chef's knife, a tough cleaver, a small paring knife and some sort of serrated blade – there are also many specialized knives that are designed for specific tasks. Kitchen knives can be made from several different materials.
A seeder is a stamp-type leatherworking tool used in leather carving. It is predominantly used in floral designs to represent the seeds in the center of a flower, hence the name. Similar to other stamp-type tools, it is held vertically over the leather and struck with a wooden or rawhide mallet to create an impression in the surface of the leather. The seeder creates a small circular impression, often similar to an asterisk with a hole in the center.
In wood carving relief carving is a type in which figures or patterns are carved in a flat panel of wood; the same term is also used for carving in stone, ivory carving and various other materials. The figures project only slightly from the background rather than standing freely. Depending on the degree of projection, reliefs may also be classified as high or medium relief.
Line engraving is a term for engraved images printed on paper to be used as prints or illustrations. The term is mainly used in connection with 18th- or 19th-century commercial illustrations for magazines and books or reproductions of paintings. It is not a technical term in printmaking, and can cover a variety of techniques, giving similar results.
This glossary of woodworking lists a number of specialized terms and concepts used in woodworking, carpentry, and related disciplines.
Leather crafting or simply leathercraft is the practice of making leather into craft objects or works of art, using shaping techniques, coloring techniques or both.
A stone sculpture is an object made of stone which has been shaped, usually by carving, or assembled to form a visually interesting three-dimensional shape. Stone is more durable than most alternative materials, making it especially important in architectural sculpture on the outside of buildings.
A swivel knife is a chisel-edged blade held upright and mounted on a pivot with a saddle for a finger. It is held somewhat like a pencil, but between the thumb and middle fingers, while the forefinger rides in the saddle above. The saddle is free to rotate and in more sophisticated models, may rotate on ball bearings.
A boot and shoe clicker is the person who cuts the uppers for boots or shoes from a skin of leather or piece of man-made material. This includes all components of the upper, including linings, facings, stiffeners, reinforcements for eyelets and zip-protectors.
The splitting band knife is a kind of knife used in several fields including: tannery, EVA/rubber, foam, cork, shoe and leather goods, paper, carpet and other soft sheet materials. It is a power tool which is very similar in operation to a band saw, with an endless loop blade; the material to be cut is supported by a flat table.
