Cutting tenons and dovetails calls for a thin blade. This 250 mm saw uses tool steel hardened to 61 HRC. The 1 mm blade stands 50 mm high, with a reinforced back that keeps the cut straight. A hand-turned wooden handle balances the pull stroke. Weight is 183 g, and a tooth guard is included.
A dovetail saw handles the shallow, accurate cuts that joinery depends on. The Kirschen 4140250 carries a 250 mm blade in hardened tool steel at 61 HRC. Blade thickness is 1 mm, so the kerf stays narrow. The blade height of 50 mm keeps cut depth predictable. A reinforced back holds the blade straight through the stroke. Total length reaches 365 mm and the saw weighs 183 g.
The fine-cut teeth are ground for work across the grain. Cut faces come out smooth and often need no sanding. The hand-turned wooden handle sits close to the palm. Curves and grooves in the grip help control the pull stroke. A tooth guard is supplied for storage and transport. Cabinetmakers, restorers and model builders use this size on small stock, pins and tenons.
The saw belongs to the back saw family. A stiffened spine along the top edge limits flex and resists warping in continuous use. That stiffness is what allows a 1 mm blade to track a marked line.
Hardened tool steel at 61 HRC keeps the tooth edge sharp over long service. The thin blade removes little material, so waste stays low and depth control feels direct. Fine teeth shear the fibres instead of tearing them. On softwood, flexible timber and medium-density species, the tool leaves a clean shoulder on tenons and pins.
The wooden handle is turned by hand and shaped with curves and grooves. The grip stays seated in the palm during the pull stroke, which helps avoid slipping. Balance between blade and handle keeps force even along the cut. Total length of 365 mm and a mass of 183 g suit bench work and mobile repair jobs.
Furniture makers reach for this saw when cutting tenons, dovetails and pins by hand. It suits fitting work on frames, drawers and small assemblies. Restorers use it on delicate components where a wide kerf would remove too much original material. Model builders and instrument repairers cut thin strips, dowels and joint shoulders with it. The short blade also works well for shallow trimming cuts on already assembled parts.
The catalog entry lists a 250 mm blade, 50 mm blade height, 1 mm blade thickness and 61 HRC hardness. Total length is given as 365 mm, weight as 183 g. Supplied features include the reinforced back, the hand-turned wooden handle and the tooth guard.
The two names are often mixed up. A dovetail or tenon saw cuts joints, pins and shoulders along straight, shallow lines. It has a stiff back, a thin blade and small teeth. A coping saw or fret saw follows curves and shaped outlines, using a very fine blade tensioned in a U-shaped frame. The Kirschen 4140250 belongs to the first group.
Match the saw to the joint size you cut most often. A 50 mm blade height sets the practical depth limit for each pass. Keep the tooth guard fitted between jobs to protect the fine teeth. Store the blade dry, since a thin hardened blade reacts quickly to moisture on the bench.
