Model: LH-20B
Best For: Carpet, house wrap, shingles, flooring, construction MRO
The OLFA LH-20B 18mm hook snap blade is built for clean pull-cuts in carpet, house wrap, and shingles. High carbon tool steel keeps the edge sharp through gritty construction work, and four snap sections per blade keep you cutting longer.
Comparison: LH-20B vs Standard 18mm Blades
Standard snap blades cut by downward pressure and can mar the surface below. The LH-20B's hook profile protects the floor, making it the smarter affordable choice for flooring installs at just $10.00.

Carpet cutting made easy
The pull-cut motion with these hook blades is so much safer and more controlled than trying to push a straight blade through carpet. Zero damage to the floor underneath in three jobs so far.

Great value at this price
Five blades for ten bucks is hard to beat, and these are genuine OLFA quality. They snap cleanly into my 18mm knife and cut house wrap in one smooth pass. Will absolutely reorder.

Does the job
Sharp, well-made, and the hook shape really does protect the surface beneath. Took me a couple of cuts to get used to the pull motion, but now I love it.
