About 9 years ago I took a chance on a “different” rotary cutter: Martinelli’s.
It has served me well and faithfully, but, after who-knows-how-many-tens-of-thousands-of-cuts, it was just worn out. I might have been able to get a replacement kit.
But, then I saw the new ones—BLUE!
And, that is how I got a new rotary cutter.
