Mine must be very old, it's one of the large ones. It seems to cut a single layer of card well but I've been trying to trim cards so there's no overlap so that means double thickness too cut.
Doesn't do that at all well, I get there in the end but it takes a few cuts.
Was just wondering if there's anyway to sharpen the blade? I thought I'd heard that if you cut tin foil it helps but it hasn't lol.
