If you only need moderately sharp blades, these should be good enough. That said, if you don't need really, really sharp blades, you probably aren't changing blades that often, therefore buying them in packs of 100 really isn't worth it.If you, like me, are obsessive about always having a perfectly sharp blade to get perfect cuts in paper or thin plastic, you should spend a few extra dollars and buy the excel bladesNo. 11 Blades Bulk, which in my experience, are much sharper.
