Lie-Nielsen Replacement Blades

A-2 TOOL STEEL

Our A-2 Tool Steel is cryogenically treated, hardened to Rockwell 60-62 and double tempered. Our heat treating technique ensures that the blade will take and hold a very fine edge for a long time. After heat treating, the blade is fully surface ground on the top, back, and cutting edge, giving a smooth, flat surface that will take a mirror finish very quickly. Our blades are thick to provide solid, chatter-free cutting.

Some folks however prefer O-1 Tool Steel, because O-1 holds up better at lower angles, 25 degrees or less, making them more useful for slicing or paring tasks. We offer O-1 blades for Adjustable Mouth Block Plane, Iron Miter Plane, Low Angle Jack Plane, Low Angle Jointer, Low Angle Smoothing Plane, No. 102 or 103 Block Plane, No. 2 Bench Plane, No. 4 or 5 Bench Plane, and No. 4 1/2, 5 1/2, 6 or 7 Bench Plane.
