This tool connects pencil stubs together

The Tsunago pencil sharpener lets you "chain smoke" your pencils by connecting pencil stubs together. The Tsunago ("let's connect") has three blades. One sharpens like a normal pencil sharpener. Another bores a hole in the bottom of one stub. The third makes a plug in the other stub. All you need is a bit of wood glue to keep the pencil pieces stuck together.

Here's some who used the sharpener for a courageous Blackwing pencil rescue.
