This is kind of embarrassing, but I will fess up. A few years ago I stumbled onto an incredible deal on EBay. I got 3 Olfa original stick style 60mm cutters, 10 Olfa 60mm replacement blades and a pair of extra sharp small pointy scissors all unused in original packaging for $39. I gave one of the cutters to a friend who is a fellow quilter. I kept the other two. I only use one for cutting and the other one stays in its package so I can see how to put everything back together after changing blades. Yes, that's right, I have one for cutting and a 2nd one whose sole purpose in life is to be a real life model showing what a correctly put together rotary cutter is supposed to look like
