In the end, it is only just a tool. Like any other tool, it has it's purposes and will operate for what it was designed to do, with the caveat that like other tools needs to be in condition to work.
And so is a rasp, or a saw, or a hammer. I use all of those, and more, for making bows. It's when you try to use a hammer to fell a tree that a hammer appears useless in your hands. If you were to throw that hammer away just because you couldn't fell the tree, what would you reach for when you needed to bang away on the wedges to split the tree? Your rasp? yeah, pound the wedge with a rasp....monumental waste of time, throw that away, too. In the end, you have an empty tool box and a field littered with good tools turning to rust.
Right tool for the right job. And I happen to like a toolbox full of good tools. That gives me more options to resolve more problems.
