CANOPUS Box Cutters Retractable, Handy Cardboard Opener, Tap Open-Close, Utility Knife Set for Boxes, Packages and Papers, Works Also as Scraper, Full Metal Body, Box of 12, Made in USA

I need to use tap knifes for work, since actual box cutters (with their heft, handles and safety releases) apparently are not as safe as these (yes that's sarcasm, I hate having to use these but whatever). I cut through A LOT of cardboard, maybe 50 to 250 various boxes every day, and I actually trim them, not just slicing through tape or along seams. The most important feature for me is that the part holding the blade inside needs to actually hold that part inside- the butt end of the inside part must be thick enough to NOT just slide right through the outer part. Tap knives that don't have a good catch at the end are completely useless, and you may be surprised how often this happens. Also, the inner part should be tight within the outer part so that it doesn't just slide around and poke holes in your pocket/leg. I would prefer a tap knife that holds a spare blade in the handle, there is clearly room and many come with this feature, these do not. But they are snug and solid and don't slip, so I'm happy. I'm also not thrilled that these have a seam, because I worry that the seam will start getting loose and not hold the inner part as snugly as it should, also, these are a bit thinner/less comfortable to hold than my favorite tap knives, however, the two I have been using the longest (a few months is a long time for me, but again, pretty heavy duty use) are this style, so I'm not really too worried, they have held up really well. I wrap a bit of cloth tape around each end for comfort/safety and to help that seam stay snug. For general purpose around the house these are great, and pretty darn good even for heavy usage if you can't use the real deal.

They come with a notch in the handle if that bothers you, but the quality its top for these.

I just love the simplicity of these old box cutters. They take up almost no room at all, and every grocery store employee in the ‘70s had one in their pocket. The fact that they still make them shows what a genius design it is. There’s no safety – this is from a time when you had to use your head, and personal responsibility was king.I bought these because I break down a lot of boxes. My recycle bin is small, so I have to cut up the cardboard into small pieces. Utility knives are great for boxes too, but they don’t work so well for scraping stickers and paint off windows. These can do both.Besides the simplicity of the tool, I love that they’re so lightweight and small. You can keep them (hide them?) pretty much anywhere, and always have a sharp cutter nearby.The inner pieces made of sheet metal arrive very sharp on the scraper ends. I dragged them across a file to take that sharp edge off, but it would have been nice if that was done before shipping.This company uses a metal grommet, instead of spot-welding the inner piece together. That grommet’s pretty sharp, too, but I cured that by using a hammer and anvil to flatten it out. I assume this was done so that an automated machine could use the holes to ensure it was bent exactly in half, but I prefer the old spot-weld technique.Out of the box, there’s no way anyone could pull or push the inner part in or out of the sleeve. The harder you try, the tighter it locks in, because your thumb and forefinger are squeezing the case tighter. The only way to use these without modification is to tap them very firmly onto a hard surface to open or close.But that’s the nature of this type of box cutter. Just take a butter knife and you can easily adjust the amount of tension you want by twisting slightly to open it up a little. If you open it too much, you can just press on the seam with the inner part removed. Super simple.Once I tweaked the cutter and took care of the sharp edges, it’s just about perfect.Pros -+ Lightweight and very small form factor – can keep one anywhere.+ Simple to operate and change blades.+ Very inexpensive.+ Goes through cardboard boxes like buttah.+ Can be used as a cutter or scraper.+  Blades are cheap , and can be found anywhere.Cons -- Too tight out of the box without adjustment.- Sharp edges need to be sanded or filed.Hope this helps.

simple, works just fine
