What an interesting topic!
IMHO it is not the branding, & not even the QC that is the huge advantage enjoyed by Victorinox.
The secret to their success is
"Fine Blanking".
I believe the Fine Blanking process was originally developed to produce watch & clock gears.
It is a process that "blanks" out (think cookie cutter) the required shape from the coils of steel, but in this case all the edges of the parts are perfectly smooth & square & the part is perfectly flat.
In the traditional blanking process, there is considerable "die tear" or "breakage" all around the edges.
For example, if Camillus was making a pen spring (double end spring), first we would blank out the spring. Then we punched the hole, then we cropped the ends. Of course these secondary operations would bend the spring, so we had to Level them (make them flat). After heat treatment we would then sand off the breakage on the inside surface of the spring. Then after assembly we would haft (sand off) the breakage on the back of the spring, along with the breakage of the linings and all the other mating parts.
By comparison, a SAK spring is blanked, heat treated & tumble polished!
Not only faster & cheaper, but hugely more consistent.
The same is true when they blank their blades & tools!
No material to be removed from the edges, no holes to be punched in secondary operations.
& no variation in any of the parts!!
So why did the American (or British!) Cutlery Industries not use fine blanking?
Firstly I do not believe the Swiss exported the technology until 20 or 30 years ago.
Then there is the downsides to Fine Blanking:
Only mediocre steels can be blanked; try to make a 440 blade (or even 420HC), break the die!
Then there is the tool costs, figure $200,000 for the pen spring die we just discussed.
Fine Blanking presses start at about $3,000,000 for a reasonable size!
After all the advantages of Fine Blanking, the SAK's then enjoy the advantages of design for manufacture.
No sanding or polishing after assembly.
No assembly pins to flare into bolsters or bone handles.
Almost every step of manufacture is fully automated. (I doubt a SAK Classic is touched by human hand except inspection!)
Don't get me wrong, I am not in any way putting down the SAK.
I fully admire the engineering that has gone into making them what they are.
But to a "Traditional Cutlery" lover like myself, they are the Bic Lighter of the knife business.
Cheap, reliable, consistent & dull.
But to ponder why Case or GEC cannot match their quality & pricing?
Wait until they produce one with 154CM blades, nickel silver bolsters & jigged bone handles, then let's talk.
