Product Description
CMT Metrik Knives 27-61/64" x 1-3/8" x 1/8" - 2-Pack (792.710.35) by CMT delivers precision planer and jointer performance in a matched pair of high-speed steel blades engineered for stationary woodworking machines. These 710mm knives are mirror-finish ground to produce razor-sharp, consistently durable cutting edges - making them a reliable choice for smoothing dry softwood, hardwood, and plywood on both planers and jointers. The 2-piece package ensures balanced, vibration-free cutting from the moment installation is complete.
Key Features
- High-Speed Steel (HS) material - delivers long cutting life and retains a sharp edge through demanding planing sessions, reducing how often knives need to be replaced or resharpened.
- Mirror finish on cutting edges - produces a razor-sharp blade surface that translates to cleaner, smoother cuts with less tearout on wood surfaces.
- 710mm total length (27-61/64" blade) - sized for wide stationary planer and jointer heads, covering the full cutting width in a single pass for flat, consistent stock removal.
- 35mm cutting depth and 35mm cutting height - engineered to seat correctly in compatible machine heads and deliver full-depth engagement for accurate, repeatable results.
- 3mm tooth thickness - provides a stable, rigid knife profile that resists deflection under load, contributing to uniform surface quality across the workpiece.
- 2-piece matched pair - sold as a balanced set so both knives can be installed simultaneously, maintaining head balance and smooth machine operation.
- Special dimensions available on request - the Metrik line can be configured for non-standard cutterhead requirements when unique sizing is needed.
Why This Product
- The mirror-finish grinding process creates cutting edges that are both razor sharp and extremely durable - meaning fewer interruptions for resharpening and a consistently high-quality surface finish on planed boards.
- At 710mm (27-61/64"), these blades are built for full-width stationary planer and jointer heads, making them a direct-fit solution for machines that require this exact length rather than a compromise with shorter knives.
- The 2-pack format ensures both knives in the cutterhead are replaced at the same time with matched blades - preserving head balance and preventing the uneven wear or vibration that can occur when mixing old and new knives.
- High-speed steel construction handles the demands of both dry softwood and hardwood planing, giving this knife set broad material compatibility across common woodworking applications.

Frequently Asked Questions
What does the mirror finish on these planer knives actually do?
The mirror finish applied to CMT Metrik HW knives produces cutting edges that are both razor sharp and extremely durable. A finer surface finish on the blade edge reduces friction during the cut, resulting in smoother planed surfaces and longer time between sharpenings compared to knives with a standard grind.
Why are these knives sold in a 2-piece package?
Stationary planers and jointers require balanced cutterheads to run smoothly and safely. Replacing both knives at the same time with a matched pair - as this 2-pack provides - keeps the cutterhead in balance, prevents vibration, and ensures even wear across the cutting width.
What material types can these knives handle?
These high-speed steel knives are suited for planing dry softwood, as well as both dry and wet hardwood. They are also compatible with plywood, making them a versatile choice for general woodworking and cabinet shop applications.
Are custom or non-standard knife lengths available in the Metrik line?
Yes - according to CMT product information, special dimensions are available on request for the Metrik Knives line, making it possible to source blades for cutterheads that require sizes outside the standard range.
