In the "Knife Lore" sub-forum in the "Knives Made Before the Year 1960" thread Miller Bro's opening post mentions square joint construction giving almost all knives with it a strong lasting snap.
As someone who has been plagued by disappointing snaps over the years (except AAPK knives and SAKs of course) I jumped on this comment and would like to know more e.g.
What is "square joint construction" and how to recognize it on a knife?
Is it still used on current production knives?
Can it be identified by a picture of the knife?
Is it commonly known, because it's the first time I'm meeting the term, not being as widely read on AAPK as I should.
