Buy ZWILLING Sharpening stone

Didn't expect a simple stone to make this much difference, but my chef's knife went from crushing tomatoes to slicing them cleanly in about five minutes of work. The stone grips the counter well so it doesn't slide around while you're working.

Took a few passes to get the angle right but my paring knives now glide through paper. The stone holds water well and doesn't dish out too fast.

My chef's knife was tearing tomatoes instead of slicing them, so I finally grabbed this stone and spent a few minutes on it. The blade glides through paper now, and cleanup afterward is just a quick rinse.
