Lol good to knowSample pack is a great idea. And you'll likely get as many opinions as there are blades. Somewhere there is a thread discussing actual objective "sharpness," measured by the ability to cut a thread, but I can't put my finger on it right now. It's probably safe to say that there's a concensus that Derbys are not as sharp as Feathers, and that's as close as you're probably going to get for agreement.
Im going to become a horder lolGet a blade sampler or two! The only way to really tell is to try things for yourself!!
