These Lie-Nielsen Fishtail Chisels are perfect for reaching the back corners of half-blind dovetails and paring or fine tuning in other hard to reach areas. Their unique shape offers versatility for right and left hand recesses. The edge is ground with a 25-degree bevel. The special O1 tool steel has been chosen because it will hold a keen edge at lower bevel angles, and for ease of sharpening. The chisel is hardened to RC 60-62, and fitted with a socket style hornbeam handle.
