Wood carving V-chisel Kirschen 3140 curved blade

Wood carving V-chisel work relies on a precise blade profile, and the Kirschen series 3140 answers that with a curved V-shaped edge opening at roughly 75°. The tool belongs to cut 39 of the Kirschen carving programme. Its curvature lets the cutting edge enter the surface gradually, so groove depth can be varied along a single pass.

The handle is turned from white hornbeam with an octagonal cross-section. The flats give a tactile reference for blade orientation and limit rolling on the bench. Blades are hand-forged in Germany, hardened in a salt bath to 61 HRC and ground at 20°. Eleven blade widths cover work from hairline detail to broad channels. Because every blade is forged by hand, cuts are not binding and stated dimensions and weights may vary slightly.

Wood carving V-chisel series 3140: geometry and build

Blade geometry and cutting angle

The V profile cuts two intersecting faces at once, producing a clean valley in one movement. An opening of about 75° keeps the walls steep enough for shadow lines in relief work. The 20° grind reduces the force needed to push the edge through hardwood. Curvature along the blade length supports sweeping cuts where the tool must rise out of the wood.

• Curved V-shaped blade, cut 39
• Cut angle approximately 75°
• Sharpening angle 20°
• Blade hardness 61 HRC
• Hardened in a molten salt bath
• Eleven blade widths in the series

Hardening in a salt bath gives even heat transfer across the thin V section. Together with the 61 HRC value, the edge holds its line during repeated mallet strikes. Carvers can re-grind the bevel at 20° without altering the original profile. The curved shank also lifts the knuckles clear of the workpiece, which matters on deep panels and hollow forms.

Handle and hand-forged construction

White hornbeam is close-grained and dense, so the octagonal handle resists denting from mallet blows. The eight flats let the carver read blade rotation by touch alone, useful when the cutting edge sits below the sightline. Forging by hand shapes the V walls individually, which is why the catalogue notes that cuts are not binding. Blades are also supplied without a handle.

• Octagonal white hornbeam handle
• Hand-forged blade, made in Germany
• Single blades available without handle
• Total length from 230 to 255 mm depending on width
• Blade widths of 2, 3, 4, 6, 8, 10, 12, 14, 16, 18 and 20 mm
• Weights from 58 to 147 g depending on size

Narrow widths of 2 to 6 mm suit lettering and fine veining. Mid widths of 8 to 12 mm handle outline work and hair detail on figures. The 14 to 20 mm blades clear longer channels and background texture faster. Keeping one cut angle across the series means a carver can change scale without relearning how the tool enters the grain.

Common applications

Sculptors use the curved V-chisel for deep V grooves on carved figures and panels. Furniture makers cut decorative borders, fluting and ornament on handmade pieces. Sign carvers rely on the narrow widths for incised letters and scrollwork. Traditional relief and chip carving benefit from the shadow depth the steep walls create. The tool works with a wooden mallet for controlled depth, or by hand pressure for shallow finishing passes on softer timber.

Catalogue reference

Series 3140 is listed as Gebogener Gaißfuß, the curved V-chisel of cut 39, alongside the straight series 3139 and the spoon bent series 3143. The catalogue page records article numbers for each size. It also lists blade width in mm. Outer dimensions and weight are included too. Figures may vary slightly. Blades are available without handles.
