Query: Easy to clean the blade, but shreds the labels

I like the fact that you can remove the blade to clean it easily. The blade has been sharp enough to open every can, but it's sometimes difficult to get the blade to lock onto the can. It consistently shreds the labels. So I usually remove the label to prevent the paper mess. The little chore of removing each can's label negates the time saving benefit of an electric can opener.
