Typewriter paraphernalia—from vintage paper and letterhead to tape dispensers and paper holders–has always fascinated me. When I received the spring issue of ETCetera, a quarterly typewriter journal edited by typewriter guru Richard Polt, I was turned on to vintage letter openers.
The article, which is well researched, has pictures of several letter openers, two of which I was able to find on eBay: a Burroughs and an A.P. Little. The latter is in poor condition but the Burroughs is in very good shape. Considering their rarity, I think finding them a coup; they were also fairly priced.
If you have a typewriter addiction, and correspond regularly, you may as well go full hilt and open letters in style.
