Thank you for viewing. I used it only once for a test sharpening, and I'm reluctantly selling it. Considering it's a lifetime item, I don't think the price is high. The surrounding area is thoroughly protected with cashew lacquer. Negotiation on price is possible. I'm also selling on other flea market apps, so don't delay. This natural whetstone is perfect for sharpening. - Size: Approximately 20cm x 6cm x 3cm - Material: Natural whetstone - Color: Gray - Usage: For sharpening - Condition: Used - Origin: Unknown
