I have to admit I have never hand-sliced home-smoked bacon. I bought a broken Globe slicer (old, very cheap) a few years ago, took it all apart, bought another junker for parts, put one together, sold off extra parts to recoup $$. Now I have a fully automatic Globe slicer I only have $100 or so into.
It does a really great job on bacon. Even better on home-smoked hams, which to me taste best sliced really thin.
