Finally have all the wrenches in, the Kelin got here yesterday.
Here's a picture of both old and new ones

It very closely resembles the old Crescent I really like.
Comparing the Klein and the Martin the Klein is only better in that it has crisp and clean ground faces on it.
The Martin is ever so slightly tighter both side to side and in and out than the Klein, although the Klein feels tighter because the spring is stiffer it's actually not any better..
The Martin is a smoother better finished forging, and is a little fatter head profile.
The Martin opens to a whole inch, the Kelin only 7/8".
