I rescued this very unique vintage Coti that lives in a labeled wooden case. It measures in at 5 x 1 3/4. It has a interesting surface heavily peppered with manganese dots. It also has angular fissures that make the surface looks to me like storm clouds. With all that is going on with this stone, it is very hard and smooth as glass, no effect at all from the storm clouds on function. I honed and refreshed a few blades on this stone. It was surprisingly fast on slurry but slow on water. Using only water, it produced a mellow Coti edge that we all love but took some effort to get there.

Don't tell us - you paid under $12 for each.
They are out there. You don't find them every day, keep looking and you will be rewarded. Some were less and some were more than $12, but there were priced by motivated sellers
Two flea market found Coti's found last month all cleaned up and lapped. These beauty's measure in at 8 x 2 and a 9 1/2 x 2 3/8. Only played with the 9 inch a little, but it appears to be fairly fast on slurry removing steel. It has a nice swirled surface with a mag Circle in the corner. The 8 inch has nice potential being very hard and slow in every way. Mag line and dots on the rather clean surface. Two nice hunks of Belgium real estate
This coticule followed me home from the market today. A natural 2" x 8" stone that is extra fat at 1 1/8" thick. Gave it a quick toss on a 100 grit diamond disk that I have been using of late to see what is under the funk. These disks on a granite slab make short work of all stones, including novaculite. Will finish it off with some higher grit and give it a good home. First picture is condition as found
