These Chinese-made cutters are an excellent alternative to the more expensive Leponitts. They are made entirely of steel (including the cutting wheels).  The handles are reasonably comfortable and the cutters aren't too heavy, although they weigh slightly more than the Leponitts.   Don't use these to cut ceramic or anything tougher; they will probably work, but you will end up with blunt blades very quickly.

Unfortunately Mosaic Workshop can't accept returns of cutting tools which turn out not to suit you, so please think carefully before buying.  If you are finding it very hard to make a decision please contact me as I may be able to lend you tools to try (you will pay a deposit, and for postage in both directions).  In the case of faulty goods we will, of course, accept returns - please see notes in the website footer.
