Slice 10512 Pen Cutter, Auto-Retractable Ceramic Blade, Safety Knife, Stays Sharp up to 11x Longer Than Steel Blades

The media could not be loaded. No more scissors to open packages. Super handy tool. It is small, easy to use, nice grip, safe and super sharp. It is retractable so you need to hold it to have the blade stick out but it is ergonomically comfortable.

I really like the friendly to fingers design, it’s unbelievable that it cuts cardboard very well and yet not your fingers.I find it clumsy or maybe awkward is a better word. The sliding button which advances the blade out to the cutting position. I think it’s a nice safety feature. I bought a different style of knife that works great but the blade stays in a locked position. I really like the knife with that exception.

This is fantastic, and works better than expected. This cuts through zip ties better than a pocket knife. I have not found something it cannot cut and cut easily at that.Several times I expected the blade to take damage or even break, nothing doing. Stood up and asked for more.Liked it so much I bought another.This is a fantastic product

broke and had to be replaced, but I am so attached to this tool now that I was willing to buy another.

Have many slice products and would buy them all again. Excellent for opening all the amazon orders.

The media could not be loaded. I was looking for a box cutter to open the constant flow of Amazon boxes that come through our place. I chose a ceramic blade because I felt that the blade would stay sharper longer and therefore just work better longer at opening boxes.When the blade arrived, I felt it was well enough made and that it was ergonomic to hold.I opened my first boxes and it cut through tape and cardboard very good, no snags or hitches.There are only two issues that I have found with this box cutter. 1. There is enough play in the blade as its mounted and relative to the handle that often times I've found the cutting motion to be to not as precise when trying to cut straight. 2. Although I understand that auto retraction is probably better for safety, I would like at least three fixed open positions, especially to open boxes which may have delicate items in them where I would need a reduced cutting depth. If I knew of the first negative prior to purchase, I would have looked for a different box cutter. If these two negative were corrected in a subsequent revision, I think it would be just right.

As advertised

If you don't need an incredibly sharp box cutter and you're not opening a ton of boxes having this is pretty useful. The replacement blades are pretty expensive so watch for that. Mine has dulled a little so I have to push down to get it to sink in at first but it works for what I need it to.
