Key Features of the SHARPAL 121N Dual-Grit Diamond Sharpening Stone

  • Dual-Grit Diamond Surface (Coarse 325 / Extra Fine 1200 Grit):
    This stone holds two surfaces.
    The coarse 325 grit side removes material fast to restore dull edges.
    The extra fine 1200 grit side polishes for a sharp finish.
    This dual setup suits rough garden shears and delicate kitchen knives alike.

  • Angle Guide for Precision Sharpening:
    An integrated angle guide keeps angles steady.
    This guide helps beginners and those who want a uniform edge.
    Consistent angles boost blade life and cutting performance.

  • Extended Through-Handle Design:
    A handle runs through the stone.
    This design adds durability and resists rust.
    You gain firm grip and control when sharpening tough tools like axes or hedge shears.

  • No Oil or Water Needed:
    The diamond surface stays effective without oil or water.
    This makes use and cleanup very simple.
    Users see little difference between dry sharpening and oil-assisted use.

  • Easy Cleaning and Maintenance:
    Dark marks or iron filings may land on the surface over time.
    They do not hurt performance and can be wiped clean using a simple eraser or Bar Keepers Friend.
    Light cleaning and gentle pressure help the stone last for many years.

  • Portable and Compact:
    Its slim design slips into toolboxes or pockets.
    This compact size makes it easy to carry for on-the-go sharpening.
