Query: steel pineapple slicer

I bought the stainless steel pineapple slicer because I had been given the plastic model. The plastic slicer did a very nice job, but I knew it wasn't going to last very long. However, for some reason the steel version is smaller than the plastic model, and as a result, the core often isn't completely cut out, resulting in some tough pieces attached to each slice. Also, since it doesn't slice as wide a diameter as the plastic model, I am forced to manually trim the pineapple that the cutter failed to remove from the outer skin, in order to reduce waste. However, the steel slicer cuts much easier than the plastic model because it's edge is much sharper. I am very disappointed with the steel model, especially since it costs 2 1/2 times as much as the plastic model.
