YES!!! They all use the same size stem, you can put a legend stem on a freehand if you wanted to and vice versa... Same goes for Danish! A freehand looks rather silly with one of those cheapie amber stems though!
Thanx Eric, I was pretty sure but wanted to be sure as I am ordering a couple pipes from MM and wanted to add a couple stems and I like the Danish stems best.
You can even buy the Freehand stems for $8 each and use them on your cobs if you like vulcanite better! I personally love the normal and danish stems more than vulcanite because they are way easier to grip in my teeth (softer). I just buy a bunch of them at a time.
