Wood Planer Blade JORGENSEN No.4 & No.5 O1 Steel 3mm Replacement

Description

Product Overview

The JORGENSEN No.4 & No.5 wood planer blade is engineered for professional woodworkers who demand consistent performance and durability. Constructed from premium 9CrWMn O1 tool steel, the blade achieves a hardness rating of HRC 62‑64, which translates into superior edge retention and resistance to wear even under heavy use. At a precise 3 mm thickness, the blade balances rigidity with flexibility, allowing it to cut cleanly through a variety of hardwoods and softwoods without causing tear‑out. The blade’s geometry is optimized for both the classic No.4 smooth plane and the larger No.5 jack plane, ensuring a perfect fit that eliminates wobble and vibration. Each blade is finished with a fine sharpening edge that can be quickly honed on a stone or diamond plate, extending the service life and reducing the need for frequent replacements. The lightweight metal construction, weighing just 6.7 oz, makes it easy to handle while maintaining the strength required for demanding planing tasks.

Usage

Designed for manual hand planes, this replacement blade excels in a workshop environment where precision and control are paramount. Whether you are shaping a fine‑grained cherry table top, flattening a rough‑sawn pine board, or preparing a reclaimed barn wood surface, the blade delivers a smooth, even shave with minimal effort. Its 3 mm thickness provides enough rigidity to hold a consistent cutting angle, which is essential for achieving flat surfaces and accurate bevels. The blade is also suitable for hobbyist applications such as model making, where delicate cuts are required, as well as for professional cabinet makers who need reliable performance day after day. Because the blade can be easily removed and installed on both No.4 and No.5 planes, users can switch between fine finishing and heavier stock removal without changing tools, streamlining workflow and saving valuable time.

FAQ

Can this blade be used on planes other than JORGENSEN No.4 and No.5?

While the blade is specifically sized for JORGENSEN No.4 smooth planes and No.5 jack planes, it may also fit other hand planes with compatible dimensions. We recommend checking the plane’s blade slot width and mounting style before purchase.

How often should I sharpen this blade?

The blade’s high‑hardness O1 steel allows for extended use before sharpening is required. Typical usage in a professional workshop may require sharpening after 20‑30 hours of continuous planing, but this can vary based on wood type and cutting pressure.

Is the blade resistant to rust and corrosion?

Yes, the O1 steel is treated to provide a degree of corrosion resistance. However, for optimal longevity, it is advisable to keep the blade dry and apply a light oil coating after each use.

What is included in the package?

The package contains a single replacement blade ready for installation. No additional tools or accessories are required, as the blade is designed for manual insertion into the plane’s existing mounting system.

Do you offer a warranty on this product?

Yes, the blade comes with a limited manufacturer’s warranty that covers material defects and workmanship issues. Please contact our support team with your order details for assistance.
