  • The Gesshin 6000 splash and go stone is a resinoid based stone with a white alumina oxide abrasive.  It is a medium hardness stone with great cutting speed and excellent polish.  It works well for a variety of tasks, including sharpening single and double bevel knives, uraoshi sharpening, and even microbevels.  It is one of the stones I use most often as a finishing stone when sharpening for customers, as it leaves a great balance of refinement and bite.  One of the things I like most about this stone is that the polish it leaves is incredibly smooth and even, which makes this one of my go to stones for wide bevels and single bevel knives.  I have found it to be pretty fast on all steels, including high wear resistance and difficult to sharpen steels.

    Like all resinoid based stones, this stone needs to be cared for carefully, especially when considering drying.  Resinoid based stones are not very porous, which often causes them to be marketed as splash-and-go.  However, some water does soak in.  My preference is to soak this stone permanently, as soaking helps soften the stone, increases cutting speed, and reducing loading on the stone surface.  If you do soak the stone, or if you think any water has soaked in, and you decided you want to dry the stone out for any reason, you will need to make sure the stone dries as slowly as possible, to help make sure the outer part of the stone does not dry more quickly than the inner part of the stone.  Making sure the stone dries in a cool, well ventilated, dry area, out of direct sunlight is best.  It also helps to wrap the stone with a damp towel to slow the drying process further.  If unaccounted for, drying too quickly can cause cracks to develop in the stone. If cracks do develop, mounting the stone to a base can help extend the life of your stone.
