This is one of the best vintage needles i have tried. There are four tip sizes for different yarn weights. They screw in securely to the base.
It is comfortable to punch with and also comes with a short loop adapter. If you are looking for versatility this is an excellent needle.
It can take rug wool to crochet cotton or embroidery thread (6 strands).
This is the only one i've found so get it now before it's gone!
It's a bit surprising since the current boye punch needles are not at all great in my books.
