My husband is relocating his bathroom and wanted something that would easily cut cement board. He LOVES this tool and it has made his job so much easier. do not damage the saw blade.
The blade works well for cutting cement boards, but after a few hits it dulls and more force is required to get a good result. I was disappointed that two of the three blades are actually a double pointed blade as shown in the promotional image. Finally, you can get the same tool for $8-$10 at Home Depot.
This made the Hardibacker good for my bathroom renovation. You'll have to pound it in a few times and apply quite a bit of pressure, but it's easy to make straight lines. I dropped it on my concrete patio and one of the two blades broke. It must be pretty fragile, but at least there are two blades so I can finish the job.
I've never tried this expensive cardboard cutter but I'm sold. It works as expected and the big solid grip makes a big difference. Gone are the days of fighting with an office knife. Cutting drywall is also much easier. 1/2 inch pad is challenging but doable. 1/4 inch boards are very easy and fast.
