Structural Difference between Kf4 and CS4

[Mr. Whippy]

I was just looking at the two side by side and noticed that on the Kf4, each side has 2 thick back springs.  On the CS4, one side has 2 thick backsprings but the other side has 3 thinner back springs.  The two tools are the same thickness overall but have different tools (as you all know  )

Just surprised that they'd differ in structure.

the construction of the juice tools is odd. the handles have no one piece construction like most tools. that is obvious but I have always thought it is weird

All my KF4s (only 3 ) have a "2 thick" side and a "3 thin" side... I wonder if yours is a mistake unique collectable, or maybe they made KF4s (or all Juices) that way at some point.

I'm Jsews will figure this out for us.

+1 on the mistake unique collectable theory.

Those backsprings are meant to line up with the inner screwdrivers. Three thin ones line up with the flatheads, two thick ones line up with the phillips and lanyard ring.

  A mystery I like it

So Mr W, if you unfold the center flathead screwdriver on your Kf4, do the other two flop out aways?

[Mr. Whippy]

I'll check it out!

Wow.  I've got a unique (badly constructed) MT!  Woot!

That's pretty cool. Pictures please

Your wish is my command:

Well.........?

Not exactly flop, but the other two have no spring resistance.  Likewise, if I pull out one of the side drivers, the center one doesn't have spring resistance.  They don't flop out however.  Great observation Bob!

A mistake unique collectable indeed!

Great. 

Now I gotta retire it and find another KF4 user...

Great.

I have a KF4 like this too, with the two wider backsprings on each side.  Mine is an older yellow one with "Leatherman USA" on the plier head.  I also have a storm grey one with "Leatherman Tool" on the head that has the three thinner backsprings behind the flatheads.

Maybe that's an older design then?  Anybody?  Bueller? Bueller?.
