Exacto is a brand that makes lots of knives. What do you, specifically, mean by “exacto knife”?
Simple silver handle with a No.11 blade, or something else?
I have found that I prefer Excel, OLFA, NT Cutter, and Yellotools knives over Exacto, and I prefer retractable breakaway blades over fixed blades. Most people keep blades in the knife for far too long after they have gone dull, and the breakaway blades makes it a lot easier to stay on point with that, not to mention that the flatter profile doesn’t roll away from you (or off the table into your foot! eeps!)
