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.

Would RecommendUsed it to cut insulation. So good my contractors stole it. Then bought their own. Easy to make deal cuts in both rockwool and fiberglass insulation. Saves time.

Almost passed, glad I didn't
Would RecommendThis knife is perfect for cutting insulation for sections that don't fit neatly into standard stud spacing. It cuts the insulation like butter; I'm glad I decided to use the right tool for the job instead of a knife I had sitting around the house.
