What it does
25 mm snap-off utility knife with a ratchet wheel screw lock that holds 100 pounds of force without the blade retracting. Two blades are included, with 7 points each, and the handle stores spares. It has a rubber safety grip and a strap hole.
How to use it
- Set the depth, turn the wheel to full clamp, then cut.
- Make one continuous stroke; do not saw with repeated tugs. Free a hung blade with the edge, not by twisting the point.
- Snap segments at the groove, away from your body, into a sharps container.

Common questions
What blades does it take?
25 mm snap-off blades. Hyde's is item 42360, sold in 5-packs (35 edges).
Why 100 pounds of holding force?
A 25 mm blade extended for a full-depth cut is under load. The screw collar clamps it rigid so it cannot creep. The 18 mm knife holds 44 pounds.
Why seven points when the 18 mm has eight?
The 25 mm segments are longer, so a standard-length blade carries fewer of them.
Can it cut carpet and linoleum?
Yes. Extend the blade, clamp it and pull one pass. For flooring over a subfloor you must not score, use the hook knife 67090.
