It’s a cool, well made thing. I looked at one, I know someone who
has it, I just don’t think I’d use it that much. It’s great for
marking/drilling/cutting a band incrementally, dividing it into
equal sections for various tasks. But personally I’m accustom to
using other methods, like a divider and graver, so I am afraid it
would mostly sit unused in a drawer if I bought it. It’s a good, if
somewhat complicated tool. But I will borrow it before I buy one. If
you think you would use it regularly then buy it.
