Korrekturmesser für Stgw90
« on: June 09, 2015, 07:00:08 AM »
So, in this thread here, marduk brought to my attention that Victorinox is now making a version of the somewhat famous Swiss Arms SG 550 rear sight adjustment tool that Wenger has made for many years. Unlike a lot of the new Victorinox/Wenger hybrids coming out this year, this knife is NOT an adaption of an old Wenger design. No, this is a 100% Victorinox design using the standard 91mm Officer Knife frame with what is, as far as I know, the first new tool added to the 91mm family since the LED was introduced in 2003. Since Victorinox doesn't make new tools very often, this is big news for knife geeks like myself. I ordered one as quickly as I could find one from a well-known SAK collector in Switzerland and it arrived a couple weeks ago. I thought I’d start a new thread share what I've learned about how this thing works. So here is the new knife:



This knife is a custom run made for a company called Grünig and Elmiger (that’s their company logo above the "T" and "H" on the front scales). G&E is a Swiss sport hunting and shooting company in Malters, Lucerne. They make and sell rifles, sights, scopes and other shooting accessories as well as sell other outdoor and shooting related items.



The name Korrekturmesser, in typical no-nonsense Teutonic fashion, simply means "correction knife" or "adjustment knife". This is the official G&E name for the knife taken from their 2015 catalog shown above. I had originally wanted to make up a name and call it something like the "Marksman" in an attempt to mimic Victorinox naming conventions. However, I figured that since G&E had it made, we should call it what they do. So, Korrekturmesser it is.

So – how does it work? Well, to understand what the new (to Victorinox) tools do, you need to be familiar with the thing that this knife was made to adjust - the rear sight of the Swiss Arms SG-550 assault rifle. Also known in the Swiss Army as the Stgw 90 (Sturmgewehr 90) in German and the Fass 90 (Fusil d'assaut 90/Fucile d'assalto 90) in French/Italian, this is the Swiss standard issue infantry rifle. The rear sight of the SG-550 looks like this:



(In this picture, the butt is to the left and the barrel is to the right). This sight allows the operator to adjust for range (how far away), elevation (how high or low), and windage (how far left or right). To adjust the range, the operator simply turns the rear sight drum and range is adjusted from 100m-400m in increments of 100m.

Elevation



To adjust for elevation (move the bullet impact point up or down), the operator turns the elevation correction screw (3) on the sight. Using the Korrekturmesser, the operator would open the elevation adjuster (shown above) and insert the barrel of the tool over the elevation adjustment screw and turn. The barrel is spring loaded and inside is a small flat-head screwdriver. Presumably the barrel is to keep the tool from slipping off the correction screw while turning it. The Korrekturmesser has a handy set of guide arrows screen printed on the scales to indicate which way to turn the tool to adjust the impact point of the bullet. Turn to the right (T) to adjust for shots that are too low (tiefe) and turn to the left (H) to adjust for shots that are too high (hohe).

Windage



To adjust for windage (move the bullet impact point left or right), the operator turns the windage correction screw (6). Using the Korrekturmesser, the operator would insert the windage adjuster (shown above) into the windage adjustment screw and turn. Turning the adjuster to the right adjusts for shots that are too far left (links) and turning the adjuster to the left adjusts for shots that are too far to the right (rechts). As with the elevation adjuster, the Korrekturmesser has a handy set of guide arrows screen printed on the scales to indicate which way to turn the tool to adjust the impact point of the bullet. The windage adjuster tool on the knife really the backspring of the elevation adjuster tool that extends out past the other tools/springs/liners at the head of the knife.

Good info as always.   :salute:  The company I bought mine from is advertising it as a Fass 90 (Fusil d'assaut 90/Fucile d'assalto 90), apparently the French/Italian name for the SIG  SG 550 assault rifle.  The rear sight tool differs in shape from the earlier Wenger.

Just noticed I duplicated some of your info.  :oops:

Cheers jazzbass - what a great post!  :salute:

I love the German vocabulary. Reading the word 'tiefe' makes me wonder if that's what the Captain in Das Boot is saying when he's ordering the Boat deeper and deeper during the calibration exercises, as everyone else on the boat is sweating with tension as the rivets start creaking.

Note to self, carve out some time to watch Das Boot again

Am I right in thinking that sight adjustment tool is the first truly new 91mm implement since the Cybertool driver and bit holder?

Ah, I was wrong, the LED light is newer.

You should seriously visit vicfan.com. All the hoopy froods are doing it.

Nice tool.  But what is it about the Swiss Arms SG-550 rear sight (2015 model) that requires T&T :ahhh

Congratulations on the very nice informations you provided and the very nice and detailed pictures.  :tu:

Don't get me wrong, since Victorinox is lacking any kind of innovation I understand all of this excitement for something "new" every 10 or so years.
However I don't get what "innovation" did Victorinox here.
They simply adapted to their 93mm frame some special tools that Wenger, NOT Victorinox, already made years ago.  :think:

I like it!  Seems like a much classier version of the old M1 Garand multi tool.
