Letter openers are easy to cut. Even with the widespread use of email we stll get enough snail mail to make them useful. I like to cut them from 3/8" thick wood but 1/4" works okay if that's what you have on hand. I like to use a spindle sander to sharpen the blade but a Dremel tool with a sanding wheel works okay. You need to take your time and get the bevel of the blade as accurate as possible.I used a #1 scroll reverse blade for the project. The interior cuts a pretty small. A dense straight grained wood works best.
