Several months ago I made an impulse buy at the local hardware store. I picked up a utility knife that came with 6 blades for $1. It was a good deal, if even for just the razors, and I couldn’t find my usual $3 knife.
Here they are, side by side. My trusty Stanley utility knife on top. This knife has a good heft, stores a few extra blades in its handle, and is slightly wider, making for a more comfortable grip. The two sides also interlock as well as screw into one another. Clicking the blade out another notch requires a small amount of force – just enough so you’ll never do it by accident – and so that it will stay in each notch as long as you don’t intentionally depress the button.
On the bottom is my no-name brand knife. It’s lighter, slightly thinner, rattles with the extra blades inside, and the button to extend/retract the blade has a little bit of wobble and play to it. Also, there’s no interlocking between the two halves.
I discovered that the seams between the two halves of the cheapie utility knife left a lot to be desired. While using the knife I felt a sharp poke in my palm. Turns out that some of the spare razor blades were poking through the incomplete seam.
So, if you’re headed to the hardware store, invest the extra $2 in the better knife. :)
