One reason you might be getting metal shavings could be due to a dull blade. If you've had the can opener for a little while the blade may be dull and need to be replaced. I'm currently in talks with an Edlund tech. support staff member and we're going to figure out what's causing the metal flakes. Other than a dull blade we'd need to know the model number of your can opener is to further assist you.
