When it comes to opening tricky plastic packaging, I sometimes have to result to super strength and even teeth, kitchen knives, and pretty much anything I can find around just to reach the product!
I have come across different types of box cutter blades and safety cutters before, but not one like the Nimble one finger cutting tool, which is a one-finger opener made of Zirconia ceramic (the same material used by cutting machinery and industrial textile blades).
If you are someone who goes through opening  mail everyday, the Nimble would definitely make the job easier, faster and more enjoyable.
The Nimble blade cuts though paper and plastic easily and the blade protrudes very minimally so it's low profile, making it safe.
With a swipe of a finger, letters are easily opened. You simply run the Nimble over the top of the envelope or chamshell packaging and the Nimble blade makes a clean cut of about 0.8mm. It really is a great product and does the job quickly and effortlessly

The Verdict
The Nimble one finger opener is small, colorful, portable and its compact size makes it an ideal cutting tool to have around the house or on the go. Being brightly colored means you won't lose it. The Nimble blade is made of ultra hard zirconia ceramic blade, meaning the blade holds a sharper edge than steel (it won't rust either). Check out the Nimble One Finger Cutting Tool By Version22
