Smith's 4" Diamond Combo Bench Stone with Coarse and Fine Grit

Smith's diamond combo bench stone features a 4-inch overall length with coarse and fine grit surfaces lined with micron-sized moncrystalline diamonds. The stone incorporates an overlapping oval hole design that collects metal filings during sharpening, reducing the debris buildup that typically slows the process. A micro-tool sharpening pad handles smaller blades and pointed implements, while a dedicated sharpening groove works specifically for fish hooks or other pointed tools. The rubber handle provides a secure grip, and the stones nest inside the handle for compact storage.
