Slicer all the way for me. I've tried the Spanto, Spearpoint, Wharncliffe, Bowie, Sheepsfoot, and the Slicer outperforms them all when it comes to...slicing. To be fair the Sheepsfoot competes pretty evenly with it, I'll admit.
But the slicer blade is also perfect for piercing, has all the strength a folding knife could need, and looks fantastic. After going through many, many Hinderers, its the only one I have left and I couldn't be happier.
