Dritz 2045 Omnigrid Rotary Cutter-28 mm, Yellow, 28 mm

I cannot get this to work efficiently and wonder if it was sold to me with a faulty, blunt blade, I've left it too late to return it as faulty. I tried with a friends cutter and that works well. I cannot find a supplier of spare blades in UK and am reluctant to import any from US. I'd love to be able to amend this review to a higher rating but can't unless I find a UK supplier. Can anyone help?

Very pleased indeed with this cutter; it does exactly what I hoped. Very easy to use and gets round the dangerous situation of leaving the cutter blade open and liable to cut you when working. Will definitely use it exclusively now and leave my other standard ones to one side. Much safer.

THis is an excellent cutter. Product arrive well packaged.
