What Customers Are Saying

This insulation knife appears to be an effective tool for cutting various types of insulation, such as rockwool and mineral wool. Many reviewers praised its ability to cleanly and easily cut through the material, with the serrated blade and comfortable handle highlighted as key features. While a few suggested a regular knife could work as well, the majority found this specialized knife to be a worthwhile investment, particularly for larger insulation projects.

Great for cutting insulation

Would Recommend

This product has a nice handle that fits nicely in the hand without causing blisters. The blade is set sturdy in the handle and is built well.

For thick insulation it’s is not as easy to use.

Would Not Recommend

I bought it instead of using a razor knife. Not sure if it was a good idea.

Don’t let the looks fool you!!!!

Would Recommend

My contractor was dubious, at first, as to how well it would cut in various situations, but came back to me about midway in the project and told me the knife worked absolutely great. I had no need for it, so I gave it to him to keep.
