So - they work well - but it never occurred to me to watch the direction of the retractable button. It’s meant to be used with your thumb so it is EXTREMELY awkward if your left handed. Tried looking for left handed ones and I guess it’s not really a thing. So it works well… but so so awkward

Cut open boxes great. Just wish they would lock open, hard to hold open while cutting. Still love them though

I bought these for work to use to open boxes and keep on my lanyard and I use it every day. Not all of them stay open but that’s ok because I feel like it’s more of a safety hazard if you forget to put the blade back down. It works just fine holding it up and using it.

I gave them to my coworkers. We work in a warehouse.

Most of these do not lock, 2 do lock and they work great the ones that lock, they are decent sizes..
