Greetings... (been out of commission a while) In December, I went to the local art supply store (Bates) to restock on single-edge razor blades, and bought a box of 100 as usual. After using a few, I realized to my surprise that they were dull. It's not the brand I had normally been getting (in a red & black box - why didn't I save it?). Bates ordered me some from X-acto. Those, too, were pretty dull. Apparently, few people use them anymore. (??) I didn't realize that this basic tool, which I carry everywhere in lieu of a knife, was going extinct. :-( Does anyone know what brand used to come in a red and black box? Or what kind you use that are sharp? ack... thanks, Liz Day Indiana, USA Need to leave or subscribe to the Sciart-L listserv?
