DIYSELF 1 Pack Utility Knife, Box Cutter Heavy Duty with 4 Pcs Sharp Blades, Storage Space in Handle, Box Cutter Retractable for Cutting Cartons, Cardboard, Boxes, and Carpet, Razor Knife

I struggled with my old box cutter to change blades. Finally I happened on this one. Blade changes is effortless. Great design. Well built cutter.

Best box cutter I’ve ever had – and I can’t believe the price! Heavy, quality piece that fits well in the hand. Holds a good amount of extra razor blades, that are both safely stored yet easy to access.

At first I thought this would be more than I wanted, way too heavy , but I'm loving the way it's doing the muscle work for me. Definitely heavy duty, sharper, easier to action, and easier to put safely away. Glad I chose it. I recommend for anyone with a heavy load.

I like the fact you can place the blade in three positions though on the shortest, the lock seems a little unstable. The big plus is how easily you can switch out the blade and not worry about your hand slipping in the process. It is heavy enough and yet easy to maneuver on the tiniest detail cutting.

Very well made, definitely recommend. Wish the blue was brighter.

Heavy duty, easy to use; just what I wanted for slicing into all my Amazon purchases!

Great handy box cutter knife. Solid and good hand grip. Can replace blade without taking the knife apart. Easily visible color. I recommend it.

I used it to dispose of heavy card board used to ship a heavy recliner. It was very easy to cut up
