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

Wish I got it sooner

works great don't know how long it will stay sharp but it works great now

Used with rockwool.

Works great for cutting Rockwool insulation. Purchase this knife instead of using the wife’s bread cutting knife.

Cutting Foam Board

This product was great for cutting the 1" foam board that I purchased to insulate my band boards. The longer blade on this allowed a clean cut all the way through the material with minimal effort. The only complaint I have is that the handle is a little smaller than I would like.

Great insulation knife

I'm cutting 7 1/4" thick rockwool insulation and this knife does the job with ease. Would recommend!

It does the job.

It works well and cuts easily through the rockwool insulation I am installing. A little overpriced for what it is, but I happy with it.

Sharp as can be

Updated my tool box with new blade knife.

right tool for the job

Perfect for cutting bat insulation, quick and accurate. Better than a razor and flat board

Great tool for the job

This knife is designed to cut rigid type insulation and was designed well. No issues using the tool and it works better than expected. Anyone that has ever had to cut Rockwool insulation knows that it has it's challenges and this knife eliminates them.

Sharp Knife

This Knife worked perfect with how it was nice and sharp with a serrated blade that made it cut through the foam insulation like warm butter.

Usefully Tool for cutting insullation

While a simple design, extremely usefully tool and great aid for cutting insulation. Spend the extra bucks to have a great utility knife for cutting great sections in insulation; used for Rockwool R-15 & Sound and Comfort.

Great knife to cut insulation

Bought this knife to cut Rockwool insulation batting. Worked great and stayed sharp.

Insulation knife

I was honestly Leary about purchasing an insulation knife with a serrated blade. Prior knives I’ve owned had a straight blade and were able to be sharpened. I can tell you I was pleasantly surprise how well the knife cut through the R19 fiberglass I was installing. Don’t know how I plan to get it sharpened but so far it has held its’ edge . I’ve installed 15 bags of insulation and the knife has shown no signs of dulling. A good knife for the price.

Awesome

Super sharp worked great. Be mindful of electrical wires barely grazed one and cut into the sheathing.

It made cutting insulation much easier than using a box cutter like I used on another project.

Handy tool

Glides through insulation, a bit more versatile than a bread knife

Cuts good, lite weight

Cuts like magic

Excellent product. Cuts like magic.
