Am I dreaming or is there such a thing as a ruler with an edge that will sharpen the rotary cutter as it is used? I'm having problems with my cutter creating a "perforated" strip instead of cutting nicely. I end up with several threads that are not cut. I've tried a new mat and that didn't help. Even a new blade, doesn't seem to be the answer. What's the problem?

It must be something in the way you're using the cutter if you still have uncut threads with a new blade on a new mat.

I am having the same issue, I don't have a new mat, but I did put in a new blade, so I will be interested in what others say. I did switch mats and still have the same problem.

I wish someone would invent one!!!!

Are you sure you do not have 2 blades in there? They can easily stick together as I found out. You should not be having this with a new blade.

often the problem. I always try pushing a new blade between my thumb and the next finger before inserting it to insure it's only one - sometimes it's two

For some reason the link won't post here but check out the Tru-Cut rotary system at I have a notion.com

If that doesn't work, try googleing I Have a Notion. They have both a blog site and a store.

I think some blades are just plain flawed. I have also put in a brand new blade, and it skips just ONE thread - at the same interval - over and over and over. GRUMBLE.

I think I did just see a picture of a newly developed ruler with a sharpening edge.

Definitely check the blade and also the angle at which you are holding the blade. Mine got a little wonky cutting the other day when I was pointing more towards the ruler than straight up and down.

For what rotary cutter blades cost, they sure don't last long at all. Wish there was a cheaper way besides scissors. Seems like after a dozen or so strips they are dull, and the last ones I bought were Olfa blades. 5 for $30. Waay too much money!
