I use the cheapest ones available, because they seem to get lost. There is an Amish place in Arthur, Illinois, Miller's Dry Goods that has them for under a dollar. I grab a double handfull ever time we go there. They are very sharp and I keep them at all my work stations, each sewing machine, the couch and family room. No excuse for not having them available. I would like to have one of those surgical ones they are posting about too.
