Thanks for making comment.  It looks as though their is a double temper line and even a ghostly shadow of a third.  Perhaps done to improve the performance of the tip of the blade? 
 
S. Al-Anizi, 
 
For me, it is not a quantity issue but rather a quality issue.  I really do not have many pieces in my collection.  When I first started collecting a real old timer that had been collecting for 70+ years told me to simply buy what I like and enjoy but focus on the best quality I could afford.
