Sorry Mike I guess you didn’t get the last word....ISKRA I do not think that is the case, scroll up a few messages and you will see a post showing three of Mike’s “later” (2014/2016) Crown Lifters each w/ a different primary blade. All three use the same later style crown lifter. Mike then posted his 2013 Radio Jack next to his 2014 Diamond Radio Jack, a nice comparison between the early and later style crown lifters...and the nick is in approximately the same location. I don’t know why the change (HELLO GEC??) but it doesn’t appear to be because of the blade shape given the use of the new style w/ sheepsfoot (Beer Scouts w/ long pull and Crown Lifters w/ nick), spearpoints (Diamond and regular Radio Jacks plus the Rendezvous Beer Scouts all w/ nicks) and clip points (Crown Lifters w/ long pull). It seems to be a production thing (2013 vs 2014/2015/2016) maybe because of a functionality issue.
Hmm, yes, I missed that ... Well, must be cosmetics then, or a production thing like you said. Something similar happened when they pushed the nail nick a bit further back on the spear points of the 2018 run.
