Chisel Irwin Blue‑Chip 38 mm — wood chisel TM444112, Irwin precision blade

Irwin Blue‑Chip wood chisel with a 38 mm precision blade (model TM444112) is designed for paring, trimming and shaping timber in joinery and furniture repair. The chisel combines a hardened steel blade with Irwin's Blue‑Chip edge treatment and a comfortable handle to provide controlled strikes and accurate material removal. The tool is intended for use by carpenters, joiners and hobbyists for a range of woodworking tasks requiring a flat, sharp cutting face.

Advantages

The hardened steel blade with Blue‑Chip edge offers extended edge retention and resistance to dulling compared with non‑treated blades. The 38 mm cutting width provides a balance between material removal and precision for common paring and trimming operations. The handle is shaped for comfortable hand positioning and stable striking, allowing controlled force transfer whether using hand pressure or light mallet blows. The overall construction supports consistent geometry for accurate shaving and fitting of joints.

Suitable for

• Paring and trimming hardwood and softwood
• Cleaning out mortises, tenons and joints
• Fine shaping of edges and surfaces in furniture repair
• General workshop woodworking and hobby projects

Key specifications

• Blade width: 38 mm
• Blade material: hardened steel with Blue‑Chip edge treatment
• Edge type: bevelled cutting edge for paring and trimming
• Handle: ergonomic handle designed for controlled strikes
• Intended use: manual paring, trimming and light mallet work

How to use

Secure the workpiece in a vise or with clamps to prevent movement. Position the chisel bevel side up or down depending on the cut and required finish; for paring, place the bevel up and use controlled slicing motions toward the cut line. For chopping or joint work, seat the chisel with the bevel facing the waste area and strike the handle with a suitable mallet if required. Keep the blade aligned with the direction of the cut and remove thin shavings rather than forcing large cuts to maintain control and accuracy.

Usage recommendations

Regularly hone the Blue‑Chip edge on a suitable whetstone or sharpening system to maintain optimal performance. Store the chisel in a protective sleeve or tool roll to avoid accidental edge damage. Use appropriate personal protective equipment such as eye protection when performing chopping operations or when working with unsecured timber.
