Rated 5.0 out of 5.0 by Greg Game Changer
Compared to using a sharp utility knife that would dull on a single cut, this literally makes the job 100 times easier. The carbide tips haven't lost any bite after a hundred or so cuts so far. The longer handle allows for a lot more force than I got with the Utility Knife. About five swipes along a clamped Straight Edge and Ive been getting a pretty clean-cut.

Rated 1.0 out of 5.0 by Mike Not worth it
Bought the scoring knife to cut concrete Hardi board. With enough patience, I'm sure this will eventually make a deep enough cut to snap the board like it's supposed to, however, I don't have that much time or energy. Other reviews and online videos suggested using the scoring knife method, so that's why I bought it. But an angle grinder with masonry wheel works way better and a million times faster (albeit with a significant amount of dust though).

Rated 4.0 out of 5.0 by rbdiy Working Great so far
I bought this to score lines on Hardie board and it's worked great on the first three long cuts. You'll want to score the line 3-4 times but after that the board will snap easily. If the carbide tip holds up for the next 50-60 cuts I will change rating to 5 stars. Very happy so far.

Rated 2.0 out of 5.0 by EMTCustoms There are much better ways to cut backerboard
I used this knife one time. It did eventually cut the backerboard, but the cut was far from clean. If you want a nice clean cut, get a diamond blade for your grinder and cut through it in 1/10th the time and get a much cleaner cut. Not sure what I will use the knife for now. Maybe I can find something else to do with it other than cutting backerboard.

Rated 5.0 out of 5.0 by HomeownerBB very effective for many tasks
I used this product to score and cut Hari-backer. I also used it to clean the grout joints to remove excess mortar prior to grouting. This is a major plus! It is thin and strong for tight grout joints with out chipping tile but still have to be careful. I have used other products to clean 1/16" grout joints that did not hold up to the abrasive nature of the grout. This tool met the challenge and keeps a sharp edge.

Rated 5.0 out of 5.0 by TommyT Handy Tool or Scoring Backerboard
This tool worked great for scoring backerboard. It made it easy to make cuts in the sheets. I also used it to remove grout between tiles. The tool was also useful for popping out spacers that had been used between newly set tiles.
