WORKPRO Ceramic Small Safety Box Cutter, Automatic Rebound Mini Letter Opener, Quick Change Retractable Blade Razor Knife, with Extra Blades

Nice quality & price. I would prefer having a locking switch so I can carry them! Easy to use, fits my hand well but I’m afraid to keep one in my pocket since there’s no lock. Simple blade swaps but Ceramic stays sharp longer than steel if you avoid hitting staples. Less tape residue buildup as well. The blade sticks out far enough to provide a decent cutting edge of 11mm / 1.1cm. Enough to break down boxes or open clamshell packages. I’m disappointed there’s no way to lock it closed; I feel like it could open inside my pocket. A lanyard / paracord would provide extra hand grip & perhaps help it stay put in the pocket, reducing the chance of getting poked. Looks great & seems durable! Weighs nothing & seems sturdy enough to handle multiple drops but I haven’t tested that just yet! Otherwise, it’s safer to use than typical razor blades. I really like them since I can’t carry a knife at work.

Comes with a couple of extra blades. Holding up after a few days on a keyring with a multitool, plastic is sturdy and has a good fit, no wiggle in any of the joints. Nice amount of force required on the spring that pushes the blade, all I use it for is opening boxes but so far it works great. Slim profile fits in the pocket well.

It states "safe for finger". Either that's a misprint or I got a set that is "defective". These are very sharp and can cut skin without very little force. Don't ask me how I know! Fortunately these have auto retract so that helps avoid injury. I also bought others here on Amazon, specifically the brands XW and STEELITE and those have been safe. Have used them many times a week for over a year and no nicks. Will continue to use those.

I bought these for work, where I routinely open well over **100 boxes a day**, cut through endless amounts of packing tape, shrink wrap, plastic strapping, and just about every other form of packaging that manufacturers can dream up. After putting them through that kind of abuse, they've earned an easy five stars. The concealed ceramic blade is surprisingly sharp. It glides through tape and shrink wrap with very little effort while keeping the blade recessed enough that I'm far less worried about accidentally slicing the product inside the box. That's a huge advantage when you're opening case after case in a hurry. The ceramic edge has also held up much better than I expected. Instead of constantly swapping blades, it just keeps cutting day after day. The compact size is another big plus. It disappears into my pocket, weighs almost nothing, and is always ready when the next pallet shows up. The safety design is probably my favorite feature. After opening hundreds of boxes during a shift, fatigue sets in, and that's when accidents usually happen. Having a tool that's designed to reduce accidental cuts while still cutting efficiently is something I really appreciate. I've used it on cardboard, shrink wrap, heavy packing tape, plastic film, bubble wrap, and countless shipping boxes. It hasn't given me a reason to switch back to a traditional utility knife. The only downside is that coworkers keep asking to borrow it after seeing how easily it cuts. Mine has mysteriously become the "community box cutter" whenever someone else's blade gets dull. If you work in retail, warehouses, shipping, receiving, merchandising, or anywhere you're constantly opening packages, this is absolutely worth buying. It has saved me time, made opening boxes easier, and held up to far more abuse than I expected. Five stars.

Indespensable tool! The magnet on the back ensures that it won’t get lost in the junk drawer - we keep it on the fridge. The blade is safe but extremely effective. Perfect for opening all those home delivery boxes, plastic packaging, heavy tape, etc. It’s small and extremely lightweight; the blade isn’t long, but we’d be lost without it. Buy two! (Great little stocking stuffer…)

These are incredibly helpful for opening boxes and cutting cardboard. Honestly one of my favorite recent purchases. They’re light and inexpensive. Easy to carry and seem to be made well enough. Great little box cutter. Blades will break the skin so use common sense when using.

It's compact to fit in a utensil drawer or your pocket without a bulge and it stays sharp. I've used the blades to scrape a glass top without fear of scratching. It opens any thick plastic packaging easily and the blade retracts as soon as your thumb moves off the slide (that's a big safety feature). Utility knives and box cutter can stay on the work bench! AND my wife really likes it.

I bought these with low expectations to replace my slice cutter. But I was thrilled with how these compared. It works just as well, it's just a bit more utilitarian in design and doesn't fit in your hand in quite the same way. The only other benefit of the slice one over this, is that it can be easily made left handed, I don't see that option on this one. But I'm right handed so it works for me. But for the price, I probably stick with these excellent little cutters.

It is easy to cut the cardboard box seal, and easy to handle. I didn't expect a replacement blade was included, it was nice surprise. I definitely recommend this product.

職場でカッター頻度が高いので、予備も含めてセット購入。軽いし歯が出しっぱにならないので安心して腰からぶら下げられます。ストラップもつけやすいし、切れ味も良いので満足してます。歯が自動で引っ込むカッターは慣れるまで使いにくいかもだけど、慣れるとかなり楽です。ただ、歯はあまり出ないので、厚みのあるものを切るには向いてないかも。ダンボールぐらいなら全然いけます。

Cuts really well and I feel like having to push it out when cutting makes it much safer to use. Small but sharp blade, yet I feel very comfortable using it!

this is a very good product as it cuts well and definitely has the safety factor. The only reason I haven't rated it higher is that I am left handed and the cutter, as built it designed for RIGHT handed people only, which makes it hard for me to give it a higher rating.

Surprised that both spare blades were broken. Suspect this happened before the item was posted as the spare blades are in a small box inside the main box that holds the two cutters. Of more concern is the "Cancer and reproductive harm" warning sticker on the box. I will certainly be returning this product.
