Ratings & Reviews for Grip-Rite 7/8-in 1 -Blade Utility Knife

Does what you need it to do.

Works great for cutting Roxul insulation.

Handy tool

I built an addiction on a house for a customer, when it came time to insulate I purchased his insulation cutter. It worked great. It's sharp and it's long enough to cut all the way throu. It even came in handy trimming off the excess foam insulation around the windows

Sharp And Durable Insulation Knife

I was looking for a utility knife to cleanup the over-expanded spray foam I did around my attic stairs when I was air-sealing my home. I found this fantastic tool and it has been great. The length of the blade makes it easy to get right up to the studs and shave the spray foam off the wood. One warning: When opening the package, make sure you open the side of the package that has the back side of the blade. I was less attentive and can assure you the blade is razor sharp!

Great foe Roxul

Holds up as well and good ergomics. It does not last forever cutting Roxul, but nothing else I have tried does either.

Works Great!

Worked great with the Safe-n-Sound insulation. You definitely want to buy this.

Perfect for Roxul

This knife is absolutely perfect for Roxul insulation and I wish I'd found it years ago. Roxul prefers not to be compacted so you need a long blade and a straight, unserrated blade takes a lot longer than this little guy.

Roxul insulatyion knife

Much better than using my wife's $300 Cutco bread knife. Full length cuts or small cuts around a power box did a very good job.

Great Tool!

On the advice of a Lowe's employee I purchased this knife to cut Roxul Wool Insulation for my new ultimate dream garage/man cave, it works great and will forever be known affectionately known as “The Sword”

Great Knife for Roxul Insulation

We installed 1,500 sq ft of Roxul Safe and Sound to the basement ceiling prior to hanging drywall . This knife did a great job and made the work much easier.

Grip rite

Good for cutting insulation for small jobs. Used to do a garage and it worked good

A good choice

I bought this to help me alter some insulation in my attic and Im glad that I did. At first I was gong to wing it with a knife of something and I bought this knife on a impulse. The knife helped speed up the process. Its the right tool if you need to alter your insulation and I suggest that you get one to prevent you from fighting your project.

good product

Good product for cutting roxul insulation. Will dull over time. Price was under $10, could be cheaper.
