I think if it is an Arkansas whetstone it would probably be fine. If it is a gray aluminum oxide brick I dunno.
I would say use a water stone. A Japanese way of sharpening for a Japanese knife.
lol Plus they work well for pretty much every other knife as well.
This one set should take care of pretty much everything that needs sharpening in the house and last for quite a while: http://www.chefknivestogo.com/knshcoset.html
Down the road if you need to replace a stone (or upgrade, add to, etc.) you still have a good foundation to build on.
