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.

Works well but there are better options
Would RecommendThis knife works well for cutting Roxul. However, I suggest you get an old bread knife - or buy a new one. It's cheaper and works better than this knife. My guess is that the bread knife is honed to a finer edge. Any knife with a serrated edge will work fine.
Inexpensive Tool to Help Complete the Project
Would RecommendWhen insulation expanded when I opened the package, the knife being long helped me cut the insulation easily. I hesitated to buy it, but I’m glad that I did.
