I just received an inexpensive Stanley 42. I do realize that it is definitely not the 42X. (I may pick one up at the upcoming Liberty Antique Show in NC) The 42 has a single plunger but it also has a horizontal plate on the back side of the blade that is meant to hold the blade in place. Is there a way to adjust the plate in and out to have it closer to the blade or is this the reason that the 42X was introduced with the double plunger. If you have had any experience with the 42, I would like to hear your thoughts.
