Edma EDM0320 Mat coup slate cutter is easy to use, long rubber grip handles makes cutting of thicker tiles upto 7mm and locking metal ring to secure cutters in closed position without opening when not in use. The jaw cutting design cuts and trims really well, all metal contruction .Finally great value for money and more important saves me a lot of time.
The best bit of kit i've bought for a couple of years. Only one problem, it becomes a bit stiff and needs lubing quite often. Don't consider anything cheaper. Good tool
