All-flat carving chisel Kirschen 3103 cut 3 series

The Kirschen Serie 3103 all-flat carving chisel is hand-forged in Germany and ground to a 25° bevel. Its blade is straight along its length and flat across its full width, a geometry catalogued as cut 3. This shape allows for even material removal and leaves a clean, level surface. Carvers use it on wood, soft stone, plaster, and similar modeling materials.

Each chisel features an octagonal hornbeam handle. The eight flats prevent the tool from rolling off the bench and help maintain cutting edge alignment during mallet work. Serie 3103 is available in sixteen blade widths, from 2 mm for fine detail to 40 mm for broad shaping. Both total length and handle section increase with blade width, ensuring balanced handling even in larger sizes. Single blades without handles are also available.

All-flat carving chisel Kirschen Serie 3103 in detail

Blade and grind

The cutting edge is straight across the blade with no sweep, described in the catalog as an all-flat profile. The 25° bevel provides a sharp edge suitable for hardwood while maintaining strength behind the apex. Hand forging imparts slight individual character to each blade, so catalog cut numbers are approximate. The blade can be re-honed on a bench stone as needed.

• Straight, fully flat blade geometry, cut 3
• Bevel angle 25°
• Hand-forged blade, made in Germany
• Cut numbers are approximate due to hand-forging
• Single blades available without handle

Sharpening should follow the existing bevel to keep the flat face true. A honed edge pares end grain cleanly without tearing fibers. When used on soft stone or plaster, the edge dulls more quickly, so frequent touch-ups on a fine stone are recommended for consistent performance. Store the chisel in a roll or rack to protect the blade corners from damage.

Handle and handling

The handle is turned from hornbeam and has an octagonal cross-section. The flat facets provide tactile feedback for blade orientation and prevent rolling on sloped surfaces. Handle size increases with blade width, so wider chisels offer a more secure grip when struck with a carving mallet.

• Octagonal hornbeam handle
• Facets limit rotation during mallet work
• Handle section scales with blade width
• Suitable for both mallet strikes and hand pressure

Hand pressure is ideal for paring cuts in softwood and for final finishing passes. A wooden or urethane mallet is recommended for roughing in hardwood. Select blade width according to the feature being carved: narrow blades for grooves and lettering, wide blades for flattening backgrounds. Always keep hands behind the edge and secure the workpiece for controlled cutting.

Sizes in the series

Serie 3103 includes sixteen blade widths. Total length ranges from 230 mm for narrow blades to 280 mm for the widest. Catalog weights range from 59 g to 253 g. Handle sections are 20 x 20 mm, 25 x 25 mm, or 30 x 30 mm, depending on blade width. Catalog notes indicate that dimensions and weights may vary slightly.

• Blade widths: 2, 3, 4, 6, 8, 10, 12, 14 mm
• Blade widths: 16, 18, 20, 22, 25, 30, 35, 40 mm
• Total length: 230 mm to 280 mm
• Weight: 59 g to 253 g
• Handle section: 20 x 20, 25 x 25, and 30 x 30 mm

It is best to select a range of widths rather than a single size. The 2 mm and 4 mm blades are ideal for lettering and fine textures. Mid-range sizes from 8 mm to 16 mm handle most modeling work. Blades 25 mm and wider quickly flatten backgrounds and reduce the number of passes on large panels and blanks.

Common applications

Woodcarving workshops use the flat chisel for leveling backgrounds, squaring shoulders, and refining faceted surfaces. Sculptors use it for soft stone, alabaster, and plaster models. Pattern makers and restorers use narrow widths to clean joints and repair carved moldings. Furniture and instrument makers use it for seat carving, relief panels, and decorative work. It is also used in craft training shops for teaching controlled paring cuts.

Catalog reference

The catalog lists Serie 3103 under Bildhauerbeitel, cut 3, with octagonal hornbeam handle, alongside the curved Serie 3112 and spoon-bent Serie 3124. Two notes apply: dimensions and weights may vary slightly, and blades are also available without handles. As the blades are hand-forged, cut numbers are provided as a guide rather than an exact value.
