I have some literature from Puma from the early '80s that gives their reasoning for using carbon springs with stainless blades:

"Es sind z.B. bei den Jagdtaschenmesser die kurzen Federn aus nichtrostfreiem Spezialfederstahl gefertigt, da sie Spannungen, insbesondere bei großen Temperaturunterschieden, wie z.B. in Afrika und in der Arktis auftreten, ausgesetz sind. Spannung infolge Temperaturschwankunkungen gefährdet aber die Haltbarkeit der Feder und kann sogar zum Bruch führen. Nur aus diesem Grunde, um die Gebrauchsfähigkeit des Messers auf einer hohen Stufe zu halten, werden vom Puma-Werk die kurzen, hohem Druck ausgesetzten Federn aus dem sehr viel leistungsfähigerem Spezialfederstahl hergestellt."

For the non-German speaking folks, they say that they use carbon springs because of their superior flexibility over a wide range of temperatures, from Africa to the Arctic.

I thought it was odd the first time I saw a stainless blade with a carbon spring many years ago, and then heard the same reasoning.
Does any current manufacturer still do this?

Not sure it's still currently done but I have an older Buck 303 with carbon springs.
 
Next on my list to clean up:

Stainless steels have to be dissimilar in composition or they tend to gall when rubbed together. This was a problem up into the 1980's and until some of the more esoteric steels became common. The gun manufacturer "Randall", makers of stainless 1911 style pistols, found this out the hard way and went bankrupt due to this (among other issues). Unless you had some pretty different "stainless" you would want to use carbon springs.

A massive Thank You goes out to my friend Herder - I was lucky enough to find a parcel waiting for me at work - I was so pleased when I opened this packet up to find two great Vintage Knives that I want to share with you......

First, this Stag Robi Klass Folder, I am not too sure as to the Pattern Name, this could be a Bartenders Knife, a Copperhead - or simply a really Nice Knife :)
The Stag has this beautiful soft Velvet feature and most typical of the German Cutlers the Stag is nice and thin - a superbly Hafted Knife, this along with triple Threaded Bolsters :cool:

Carbon Springs with Rostfrie Blades - there must be some reasoning for this, were the Manufactures more trusting in the Carbon for Spring re liabilities rather than Stainless?

The walk and talk is butter smooth if that makes sense and another neat feature of this knife - when the Main Blade is in the open position- you must press the Pen Blade further into the Liner to release the Main to Close the Knife - not a new thing but not an all too common thing either, the build of these Vintages always leave me thankful that I am fortunate enough to have this hobby that forever fascinates me.

Early Robi Klaas Knives really are right up there with Quality- I haven't seen one that disappoints me yet, the later year manufacture of these knives tells the all too common theme as it does with many of the Cutler firms with cheaper manufacture processes etc - but make no mistake...... the Vintage Klaas Knives are that...Class!

Here is this Classy Klaas...

Like our ever favourite TV adds say "But wait - there's more"......

Now this little knife - like all vintage Pen Knives - often leave the beholder shaking their Head- the craftsmanship to build such a knife such as this..... well we all know who hang out here .......or should I say We WISH to know just how much talent it takes.
So...... included in the package with the Klaas was this tremendous LF&C USA 03634 Whittler.... Oh man... did these guys build a knife!
To smash all these Blades into such a refined area- to also the give the Walk and Talk of a knife any Custom Knife maker dreams of :eek:
The small things of such a knife like the crooked Long Pull of what the Knives of yesteryear sported- often through blade take down - but in this case- the Knife has had little use!!!The beautiful Swage work - done by hand because when you look hard at this knife- the slight unevenness of the Swage work is there- which in itself creates a beauty that only an old Knife hold, each Blade carries this superb Swage Work.
Small things like - trying to actually spot the end of the Brass wedge between the Springs is a difficult task - it just simply disappears to such a wee thin tiny tip a magnifying glass is your friend to complete such a task!

For such a small knife @ 3 & 1/4 inches closed- the Main Blade's Spine is super thick that of course meets the Splitback Springs perfectly, check out the above photo of just how closely these Blades nestle in to each other- believe me there isn't a tiny bit of Blade rub!
LF&C's "Perfect Stag" is in perfect order!
And on top of all that- LF&C's "UNIVERSAL" Etching remains prominent on the Main Blade :) :thumbsup:.

Amazing old knives my friend . I obviously I like the Klass more than the LF&C because of the Stag but I do admire the craftsmanship of a split back whittler . I assume that the LF&C covers are that Gumfuddy stuff ??? If it were possible I would send you this old wooden box to go with the LF&C . Just ignore what may be shown on the top of it . You may recognize the Case as the one that you very generously gifted to me my friend .
