Marking Knife
A knife with a sharp point or blade used to scribe precise layout lines on wood and material.
What is it?
The marking knife scores a fine, precise line against a square or straightedge, cutting the fibers rather than drawing a broad pencil line. The result is an exact reference for a saw or plane to follow.
What is it used for?
- Scribing precise layout lines
- Marking against a square or straightedge
- Cutting fibers for a clean guide line
How to choose
Choose a single-bevel blade for flush marking against a square, or a double-bevel for freehand. A sharp, replaceable blade stays precise.
Anatomy
Understanding the parts of a marking knife helps you use, maintain, and buy it with confidence.
- Body: the main working portion of the tool
- Working end: the part that contacts the material
- Handle: the part you grip for control and leverage
Materials & construction
Quality marking knifes are made from hardened, heat-treated steel (often chrome-vanadium or high-carbon) chosen for strength, edge retention, and resistance to wear and corrosion.
Safety & maintenance
- Inspect the tool before use and replace any that are worn or damaged
- Use the right tool for the job and apply controlled force
- Store tools clean and dry to prevent corrosion
- Wear appropriate eye protection for the work
