These letter openers are cheap but work the best from what I have found. A lot of the more expensive ones get stuck but these just glide right through. Definitely would suggest these.
It's okay and it gets the job done. But the one thing I don't like about it is that the point where you insert it into the envelope is too wide. I prefer the one that's narrow at the tip because it's easier to use. I'm getting some more of these only because the ones I really want are out of stock.
You may think something as simple as a good letter opener is insignificant. It isn't when you open a hundred or more envelopes a day however. This simple letter opener opens letters quickly and effectively. Good-by paper cuts to my fingers! I have bought these to give to my friends and co-workers too! They make thoughtful inexpensive little gifts.
