Semi-useless: Electric can openers. The can opener part goes to hell in a hurry but the knife sharpener lasts forever.

Let me guess: you have an electric can opener that doesn't open cans but still sharpens knives ~ yes? ~ LOL! ~ the best can opener, bar none, is the Swing-Away manual ~ I bet I've had mine for at least 25 years ~ but, granted, I don't use much canned foods ~

Several of different brands... and all have the same problem.
No more! We're back to our regular el-cheapo hand can opener. Was bought for a couple of dollars years ago.

I have a Swing-Away that's just about as old as yours, Sooz. I swear by it. If I want a knife sharpened, I have a wet/oil stone and a honing rod to do that job. Old school stuff.

Easy fix. Drive a knife through the top of the can and then cut the top off. Use sharpener to resharpen knife. Voila! Can opener still works.

I've got a little all metal hand can opener that has got to be at least fifteen years old and still works like a darn.

Probably the same as our el cheapo like this one: http://en.wikipedia.org/wiki/File:Can_Opener.jpg

we have a hand held. when that doesn't work, or we can't find it, we beat cans against rocks.

That's how you do laundry.
Now we know your cans are clean.

That's the one!

Best can opener ever invented.
