DIYSELF1 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

Nice balance, non-slip vinyl grip, carries extra blades, easy to swap out old and bring new one in from the auto load carry blade bay, comes with 4 blades, but holds ten. I could cut up all the boxes in a box store. Good price, and so much better than my old time old style Stanley box knife. My wife uses this new box cutter for all her eBay and Amazon store seller items.

Good for heavy duty work. I used it to cut self-adhesive backsplash tiles.

This thing is big and beefy. It has good ergonomics. What I like best is you don't need any tools to change blades or to access the spare blades. A lot better than I expected for the price. Solid, steel, and heavy. (except for the door of the spare blade compartment, which is plastic)

Overall a nice option. Compaired to other box cutters, this knife feels extra large and a bit hard to hold on to. If you have Extra large hands this should be fine, My hands are large and at times I feel this knife is just a bit too big. Overall It is well built and a good choice.

Balanced. Easy to grip. Good quality
