Sonuimy 2-Stage Retractable Ceramic Mini Box Cutter, Safety Box Opener with Lock, Magnetic Package Opener Keychain, Small Pocket Utility Knife Tool Knives for Warehouse Office Work Cardboard -3PCS

These are inexpensive, safe box cutters. They have a lock if needed to keep the blade from extending accidentally. The blades are ceramic are thick and sharp enough to cut box tape, but not really sharp enough to cut skin unless you mean to.I really like them. They're effective for their intended purpose, but safer to use that cutters with metal blades.

Compared to the slice versions, these are cheap. But this is exactly why I bought them. The build quality is solid. Not high-end apple designer worked on for 3 years straight, but a solid fit in your hand and get the job done design.A no-nonsense box opener is what I wanted, and I got three of them for less than I would have paid for one slice. If you haven't used a ceramic knife you don't know what you are missing. Easily open all those Amazon packages without the sticky tape residue, cuts right through the plastic blister packs, and I use mine to carve up the cardboard to fit my recycling bin.As a side note, the blade is not super sharp to the touch, but it rips through everything I have tossed at it. This is not as safe for fingers as the rounded Slice product, but more like the sharp versions of slice.Why aren't all knives ceramic? Ceramic is very hard, and thus hard to sharpen. This makes it last a long time, but unless you have a diamond sharpener once it is done it is done. Ceramic is also very brittle, so you can't use it as a chopper, or bend it like a steel blade. When I say it lasts a long time, the ceramic blades I have cut everything like warm butter after many years of use.

I have a toddler in the house so I decided to purchase safe Box Cutters to eliminate the chance of an injury. This set is a great value and I like that the Cutters have a magnet built in to store on the fridge and also lock and have 2 blade adjustments.It is crazy how well these work to cut paper, tape, and even cardboard. They slice right through but somehow the blades are not sharp to touch. I have accidentally run my finger across the blade firmly with no cut or damage to my skin yet the blades effortlessly cut through packages.
