This would work with regular shaped blades, right? Like this? https://www.amazon.com/gp/product/B01GIZ9164/

Yes any standard sized utility knife blades should fit. I tested a bunch of different brands from my local hardware store.

FYI those are stupid expensive. Your can get 50-75 for that price at your local hardware store.

Ceramic?
-
Ahhh, nope I was thinking of normal steel blades.
How do the ceramic blades hold up? I’d be a little worried about chipping or cracking.

They're apparently shit for anything not cardboard, but they really shine when the only thing you're cutting is cardboard.
I wanted to test that for myself.

Rad, I wish they had these when I was matting tons of stuff in art school. Though I probably wouldn’t have been able to justify the price.
