What Customers Are Saying

Customers overwhelmingly praise this insulation knife for its exceptional cutting performance through rockwool, fiberglass, and foam with minimal effort, delivering smooth, precise, square cuts that transform a tedious task into a manageable one. Reviewers consistently highlight the durable, razor-sharp blade that maintains its edge through extended use, paired with a comfortable, lightweight, non-slip handle that reduces hand fatigue and prevents blisters. Many appreciate the high value for the low price point, calling it a must-have for insulation work. A few note the handle could be larger for bigger hands or mention limitations with thicker foam, but these minor concerns are vastly outweighed by overwhelming satisfaction.

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.
