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

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.

I only use on stretch wrap, tape and cardboard. It performs great. I like the locking feature. I’ve used it for a week and no sign of dulling. I will definitely order more. I like the compact design well.

These little things work way better than I expected. Cuts with ease and still looks and feels like new. Great for small hands!

I love all the cute mini cutter products that have come out in lots of different shapes and colors (purple cloud, anyone?), but they all looked SO SMALL. That might be fine if you have small hands, but I have fairly large mitts for a woman. So, these seemed more my speed. The plastic holder is still a little small, so it's a little difficult to hold comfortably but I'm not holding it very long. It's not the sturdiest of plastics, but it's fairly high quality. The lock button is AWESOME. Easy to use and holds the blade in place. The ceramic blade is really cool, but it will still cut flesh (ask me how I know). It does have trouble cutting my washi smoothly, but I should probably be using an Xacto knife for that. I love the 3-pack so I can keep them in multiple places that I need them.

My original order wasn't that great (see review below which I am leaving for posterity sake). Seller reached out and contacted me and sent a replacement set where I did get all 3. These are SAFETY CUTTERS, if that is what you are looking for, then these will fit. They won't cut skin without trying harder than I went, pretty much can't accidentally slice the way real sharp ceramic dangerous blades can. Even though they are skin-resistant cutting, they DO cut taut tape on a box or paper laid on a hard surface. These also have the side lock so I would not be concerned about them around a child when locked except as a choking hazard. The seller is extremely helpful and my review below was a case of ME Not Reading The Description! These are great for light cutting work where what needs to be cut is clearly defined and in tension and preferably against a flat, hard surface. Then they will cut. Trying to cut through cardboard puts you in a situation where you might be pushing too hard and actually be able to nick your finger with it but I don't think most cushy flesh on fingers would slice easily, while a knuckle would, so practice blade safety and always cut away from yourself and never have a body part in the path of a blade in the even it slips. Seller is amazing customer support, so ask them if your use is best if not sure! ———————————————————————————— Very Dull. I thought this would be like the Ceramic UT1 blades which can chop through 2 layer cardboard as easy as paper. These can't even cut free hanging paper, they catch and rip and can only cut something when it is taut. Access to bevel is blocked by the holder so I am unable to hone them on my diamond wheel which I sharpen the utility blade ceramic blades to scary sharp with. Those are amazing. These Are NOT SHARP. Also, I only received 2 in my package, red and blue.

Great little gadget! Works well!

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.

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.
