I was just removing lots of tiny little bits of paper from my Seklema mat and, skimming the forum. The post from @Carol about using a lint roller made me wonder if this community is aware of the Lil Chisler tool. I think it is pretty well know among CNC cutting machine users.
After running a job, I can just scrape all the bits off into the trashcan. It is also useful for smoothing down a substrate like paper to make sure it adheres evenly to the mat before running a cutting job.
You can mostly do the same thing with an expired credit card, depleted gift card, etc. The beveling on the Chisler makes it a little easier to work with, though.
