Used a letter opener at the office and never had one at home. This is for home use. It makes it so easy to get an envelope open and it's nice and neat afterwards if you want to keep the contents inside the envelope for later use.
As a former secretary/administrative assistant I always used a letter open at work. I decided I would use one at home too and it really makes things much easier for me. You get a nice clean opening of the envelope. If you want to save the contents in the envelope after it is opened it just looks neat with no raggedy tears.
I needed a letter opener but did not really want to pay a large amount for one. I found this and figured for the price why not. Glad I did I liked it so well I went back and bought 3 more one each for my daughters in college and one for my husband serving in Iraq who was in need of one. Nice price for a durable slice...
