Some more measurements of the two clip mains:
Measurement ----- #78 American Jack ----- #86 Oil Field Jack
thickness (center pin) ----- 0.544" --------------------- 0.630"
thickness (tang) ----------- 0.112" --------------------- 0.112"
thickness (behind edge) -- 0.009" --------------------- 0.008"
depth (widest part) ------- 0.662" --------------------- 0.754"
Weight in grams --------- #78 ----------------------- #86
------------------------------- 93 g ------------------------ 105 g
SteveC apparently measured a newer release spear main #78, while my older clip main #78 has the same thickness blade stock as the #86.
