Keep your increment borer sharpened and working its best with this Large Cork Work Rest accessory. Designed to support and stabilize your tool while sharpening or honing the cutting edge, this cork piece helps you maintain consistent contact between the borer bit and sharpening surface.

By resting your tool on this cork while you hone or sharpen the bit, you reduce slipping and uneven pressure, making maintenance easier and extending your tool's life. Whether you're a forester, researcher, arborist, or field technician, this large cork work rest is a practical, low-cost accessory that helps you care for your core sampling equipment.
