Water slipstone (or whetstone), conical and knife shaped. It is also available in larger size. Thanks to its rounded edges it is an excellent slipstone to use when sharpening the inside of, for example, spoon knives and gouges.
Size: L60 x W23 x H6 x H2 mm
We sell Japanese slipstones in three different grit sizes. Grit 1000, 4000 and 8000. When we send you our tools, they are honed with the slipstone of grit 8000. This is the finest slipstone and will give the same sharpness as stropping the edge with a polishing disc of wool. In other words, it is razor sharp. To achieve the highest level of sharpness you need all three grit sizes. Start with the coarsest slipstone if the tool is really dull, and gradually move on to finer grit. If the tool is just a little dull, you can just hone it with the grit 8000 slipstone to get it razor sharp again.
