My grandmother had one of those in a kitchen drawer.Back in the 60's there was a sharping gatget, that was pretty cool. Have not seen it in years. It was cylinderal. About 2 1/2 in. in dia. It was like two wheels with a stone between them.. You put the knife blade between the stone and the wheel. Then rolled it back and forth. Right side, then left side. It worked well. Would really like ti find another one.
