Structural Difference between Kf4 and CS4

[kd8fre]

I have an interesting KF4.  On the flat-head screwdriver side, it has a 0901 date code. on the other side, there is no date code that I can find.

Mine has the 2/3 backspring arrangement.

Try looking under the screwdrivers for the date code.

Well, there it is.  Both halves are 0901 date codes.

Yep Nate I reckon you are right on the 2 spring set up being a early production deal. I had a look at my 5 Juices , my Pro is a 0602 , Kf4 0202,SC2(clear)1202 & SC2(blue)0203 all have the combined 2 & 3 spring set up. My XE6 is a 0401 & it has a 2 & 2 set up.


Quirky XE6

Standard Juice set up , Pro.


XE6 sports early pliers.



My XE6 is a bit different in that it has no model identification on it's scales. I think it missed out on the process as opposed to having the markings removed 

Mat, I believe I have the identical twin to your quirky Xe6. Mine has 2 & 2 backsprings, 0401 date codes, and no markings on the scales whatsoever.
