Review on Hultafors 603000 Grinding Stone: High-Performance Sharpening Tool for Superior Results by Keith Samuel

Works well. The finger area is perfect for protecting your fingers and gripping the stone. The leather case is good. It took me a while to figure out what the perforated tabs were for. But if you tie the ends of the leather straps and thread them through each pull tab, you can create a hanging loop that you can attach to your belt or backpack.
