This may be a silly question, but, do you find that you have to tighten your rotary blade from time to time as your working on cutting your fabric?

Yes I do, but I have a hard time tightening it down real tight.

Occasionally, but not often at all.

Yes! Thought I was using it wrong or something :)

On my older ones. I have not had to with my newer easy to change one.

Yes, my blade gets loose occasionally. It's made by Fiskers.

No, not on the Martelli. I did on my Fiskars.

Yes on occasion. Seems I either get too tight so it won' turn or have to tighten because left it too loose and it got looser.

The first one that I used had the trouble of the blade coming loose. I recently got a deluxe rotary cutter and the blade does not come loose. Try getting a olfa deluxe and see how it works for you.

Yes, I do.
