Replacement Plane Blades & Parts for Hand Planes

Replacement Plane Blades for Block, Smoothing, Jointer & Rabbet Planes

A sharp, well-fitted blade is the single most important factor in a hand plane's performance. Infinity Tools stocks a focused selection of replacement blades and chipbreakers sized and ground to fit specific plane models, from classic block and smoothing planes to specialty rabbet and skewed-rabbet planes. Whether you are restoring a vintage tool or upgrading a budget plane with a better blade, precision-ground steel is the most cost-effective improvement you can make.

Chipbreaker sets for common joinery planes are stocked alongside the blades themselves, so you can replace the full cutting assembly at once. The replacement blade and chipbreaker for jack and smoothing planes and the replacement blade and chipbreaker for jointer planes cover the bench planes used most frequently in furniture making and general woodworking.

Specialty planes are also represented. The replacement blade for double rabbet hand planes and a 24mm replacement blade for skewed rabbet planes address common specialty cuts. The Clifton block plane replacement blade fits Clifton's premium block plane and is made to the same standards as the original.

Choosing the Right Replacement Blade

Before ordering, measure your existing blade's width, length, and thickness, and confirm the blade angle your plane's frog accepts. Rabbet and specialty plane blades such as the 30mm rabbet plane blade and chipbreaker are sized to fit specific body widths, so confirm the measurement against your tool. Scrub plane blades like the wood scrub hand plane replacement blade feature a pronounced camber ground into the cutting edge — a detail unique to scrub planes that should not be substituted with a flat bench plane blade.

Block plane blades: check body width and blade bevel angle
Bench plane blades: match to plane number (e.g., No. 4, No. 5, No. 6, No. 7)
Rabbet and specialty blades: confirm width in millimeters
Chipbreakers: must match the blade width exactly

Frequently Asked Questions

How do I know which replacement blade fits my hand plane?

Measure the width, length, and thickness of your existing blade and note the plane's model number or type. Bench plane blades are typically sized by plane number (No. 4, No. 5, etc.), while rabbet and specialty blades are listed in millimeters. Confirm these dimensions match the product listing before ordering.

What is a chipbreaker and why does it matter?

A chipbreaker is a secondary iron that clamps onto the flat face of the main blade, bending the wood shaving sharply as it exits the cut. This breaks the chip before it can run ahead and tear the grain. Proper chipbreaker fit and distance from the cutting edge directly affect surface quality, especially in figured or reversing grain.

Can I replace just the blade, or do I need a new chipbreaker too?

In most cases you can replace only the blade, provided the new blade's width matches the existing chipbreaker. If the chipbreaker is bent, corroded, or otherwise damaged, replacing both together with a matched set such as the jack and smoothing plane blade and chipbreaker is the most reliable approach.

What is the difference between a block plane blade and a bench plane blade?

Block plane blades are narrower, shorter, and typically bedded at a lower angle — commonly 12° to 20° — with the bevel facing up. Bench plane blades are wider, longer, and sit bevel-down on the frog, usually at 45°. The two are not interchangeable.

Are replacement blades sold as a matched pair with chipbreakers?

Some listings, such as the jointer plane blade and chipbreaker set, include both pieces. Others, such as the Clifton block plane replacement blade, are sold as a single blade. Check each product listing to confirm what is included.

What steel is used in Infinity Tools replacement plane blades?

Infinity Tools does not publish a single steel specification across all blade products, as offerings include blades from multiple manufacturers. Check individual product descriptions for steel type and hardness details. If you have questions about a specific blade, contact the Infinity Tools team directly.

Do scrub plane replacement blades have a cambered edge?

Yes. The wood scrub hand plane replacement blade is ground with a pronounced camber across the cutting edge. This curvature is intentional — it allows the scrub plane to rapidly remove stock across the grain in aggressive, overlapping passes before final surfacing.

What hand plane does the Kunz Plus No. 4 or No. 5 replacement blade fit?

The replacement blade for Kunz Plus No. 4 or No. 5 is made to fit the Kunz Plus line of bench planes in those two sizes. The No. 4 is a smoothing plane and the No. 5 is a jack plane; the blade dimensions differ slightly, so confirm your model before ordering.

Does Infinity Tools offer a quality guarantee on replacement plane blades?

Yes. All Infinity Tools products are covered by the company's quality guarantee. Full terms are available on the quality guarantee page.

Where can I learn more about sharpening and caring for hand plane blades?

The Infinity Tools learning center at infinitytools.com/blogs/learn covers hand tool techniques including sharpening, honing, and blade setup. It is a useful reference for both new and experienced woodworkers.
