They are usually cut down to match the size and shape of the object being worked on. While crystal stones are soft and difficult to cut into smaller pieces, the Sanwa Suruga Whetstone can be cut without losing its shape.\u003c\/p\u003e\n\u003cp data-start=\"919\" data-end=\"1171\"\u003eHowever, cutting them is quite a task. Without tools such as a grinder, it can be difficult.
