Wood tenon saw 250 mm 61 HRC Kirschen 4150250, fine cut

A wood tenon saw earns its place in the workshop when cuts must stay narrow and clean. The Kirschen 4150250 belongs to the German fine-tooth backsaw family. Its blade runs 250 mm long and is hardened to 61 HRC. That hardness lets the tooth line hold its cutting edge through repeated work. The thick reinforced back stiffens the blade and keeps it tracking straight.

Blade dimensions of 250 × 50 × 1 mm give a thin kerf and a smooth cut face. Joiners reach for this saw on tenon shoulders, dowels, slender battens and decorative parts. Total length is 380 mm, so balance between blade and handle stays predictable. Hardening is controlled to keep blade hardness and back stiffness in step. A tooth guard is supplied for storage and transport.

Wood tenon saw Kirschen 4150250 with 250 mm blade

The 1 mm blade thickness is the defining figure here. It removes little material per stroke and leaves a narrow, clean kerf. Combined with a 0° grinding angle and 61 HRC steel, the tooth line stays consistent along the cut. The stiff back rib resists sideways flex, which is what keeps a tenon cheek flat rather than wandering.

Blade geometry and hardness

Blade length of 250 mm suits joints cut by hand at the bench. The 50 mm blade height sets the maximum useful depth of cut, while the 1 mm body keeps the kerf tight. Material hardness of 61 HRC limits edge rounding during continuous sawing. The grinding angle is stated as 0°, matching a fine crosscut tooth line for finishing work.

• Blade size: 250 × 50 × 1 mm
• Material hardness: 61 HRC
• Grinding angle: 0°
• Total length: 380 mm
• Fine tooth line for smooth cut faces
• Thin kerf for close-fitting joints

Because the tooth line is fine, feed pressure stays light and the cut is easier to steer. Start the kerf at a shallow angle, then bring the blade level once the groove is established. On thin stock, support the workpiece close to the cut to avoid breakout. The narrow kerf also reduces the amount of paring needed afterwards with a chisel.

Reinforced back, handle and tooth guard

A steel back rib is fitted along the top of the blade. It adds rigidity, dampens vibration and holds the blade straight under load. The handle is sized for a stable grip and gives clear direction when working thin material. Height of the saw measures 25 mm and weight is around 205 g, so the tool stays controllable in extended sessions.

• Reinforced steel back for blade stability
• Height: 25 mm
• Weight: approx. 205 g
• Width across the blade: 250 mm
• Tooth guard included for storage and transport
• Balanced blade-to-handle proportion for guided cuts

The guard clips over the tooth line and keeps it protected in a tool roll or drawer. Store the saw dry and wipe the blade after use to keep the surface clean. Keep the back rib seated and unbent, since any distortion there transfers straight to the cut. Sharpening should follow the existing fine tooth geometry.

Common applications

Tenon shoulders and cheeks are the main task for this saw. It also cuts dowels, pegs and wedges to length with minimal tear-out. Cabinetmakers use it on small mouldings, beadings and decorative trims. Model makers and instrument builders rely on the thin kerf for slender parts. In furniture assembly, the saw trims protruding dowels and joint waste before final paring. Traditional hand-cut joinery, where accuracy matters more than speed, is its natural field.

Catalog technical data

Catalog figures list the grinding angle at 0°, material hardness at 61 HRC and a blade of 250 × 50 × 1 mm. Recorded dimensions are 380 mm length, 250 mm width and 25 mm height, with a weight of 204.82 g. The saw is supplied with a tooth guard. No further tooth pitch or set values are stated in the available source data.

Used within these stated figures, the saw covers fine crosscutting and joint work on solid timber. Match the blade depth to the stock, keep the cut supported and let the tooth line do the work. For deeper or wider cuts, a longer backsaw or panel saw is the more suitable choice.
