I have a question for the rotary cutter users regarding sharpeners, does any one have a sharpener? I am looking to purchasing a stone sharpener, it is the kind you leave the blade in the cutter while you sharpen. The reviews have been mixed, but many more good than bad. I was just wondering if any one has it and if they would recommend it. It is called the True Cut Rotary Blade Sharpener. I can get it on Amazon for $25. and if there is a better place for me to ask this question please point me in the right direction. thanks
