I use 1/4 round bits on almost everything I build, mostly western red cedar patio furniture. I always round the grinder, so I don't always pay attention to how well the edge of the router actually does. And it's pretty hard to tell when your router has worn out. Freud's a pretty good name, so I tried out one of her snippets and was amazed at how much it had changed. Regrinding was almost not necessary.
