Mid-Size Medium-ish Coarseness Natural Oilstone for Sharpening & Honing

Vintage Natural Oilstone Sharpening Stone. No identifying markings anywhere on the stone to indicate original manufacturer. Appears to be a nice multi-colored natural stone and has no cracks. There are a couple very small nicks out of some of the corners. The stone measures approximately 5" Long, 1-5/8" Wide, and 1/2" Thick. This stone has been lapped flat on all sides. Perfect for immediate use on those knives, chisels, plane irons, or any other blade where a sharp edge is essential. See pictures for details. Let me know if you have any questions.
