Can Opener Sieger Needs Cleaned Up

Sieger brand German can opener that works completely different than American types. You force the cutter through the can, then drag it around the edge. This design was popular in Germany for a long time and cheap crappy versions are still available in stores. This is an earlier style, made from steel and wood. It is in OK condition with some wear and rust and it really needs a good cleaning. It is usable and the cutter and teeth are still decently sharp.
