Review on Zoid 3-In-1 Adjustable Utility Knife With Contoured Body And Trax-Grip For Safe And Easy Cutting, Functions As A Precision Utility Knife, Wire Stripper, And Carabiner, Box Cutter, Wire Cutter by Mike Littlejohn

I buy those snap knives for under a dollar and when I get to the last snap, I often just consider them disposable. Not only do I realize that this practice creates an unnecessary expense, but it’s adding to the landfills one little piece of plastic at a time. I’ve decided to just replace the blades moving forward and only throw away the handle when the handle actually breaks or fails to work anymore.I found this 50 pack and put one of the blades in my old handle. It fit properly and securely. I don’t know if all handles for the 9mm inserts are built to the same manufacturing tolerances so your handle may provide different results.The blade was sharp out of the package and I tried it on some cardboard and other thicker substances. I didn’t push it outside the limits of what a normal person would use a blade this size for. It held sharp. I haven’t tried to snap off a segment yet but it looks just like the original blade that came with my knife and I suspect I will have the same experience with snapping it down.These blades do the job and will save you money over time versus replacing those cheap snap razors. The 50 pack will last most users over a year. Happy cutting!
