I know some have questions on the numbering system because of the number used on the box and on the tang of the blade. These numbers are different with for example the TT03 Filix got the identification
for the model, name and color KNI.0070.2060 on the box. On the backside of the tang for the blade the number is A17-52 and as you see on the picture the TT03 red is A17-51. The two last digits is then the difference in handle pattern/design as I see it. What
is most important knowledge is that the tang numbering represents the production with model type. I believe it is Swiza Company identification for the model and additional information regarding protection of the products. That the blade got numbers and identifications
mean that Swiza can look into the production numbers for this model and find when it was made and additional information. If knives somehow should be sent back to them it is easier. I will look into it because I need 100% information to be able to be fully
sure. What we can learn from the numbers is that each similar knife does not have separate numbers. That I would believe is done by engravings and other methods on other parts of the knife. The backside tang stamp can have limited numbers still.
I can see that in the same batches of knives there is very little difference if any on them. I have found production variations on Swiza
knives buy these are not from the same batch. There are some variations on the locking mechanism, edge and other as well.
On Swiza knives you find the emblem and the Swiss Made designation.
The backside of the tang numbers indicates further protection and identification. This is my information so far and as soon as I find more I will post it.

Further on numbering system research:
Here is why i need 100% information on the blade numbers and an alternative theory
on it.
Above this last post I mentioned the difference in the numbers but it is not so easy to make it out 100%. I wonder too if the numbers are not always related
to distinguish models from each other. For example on the D04 scout knife that you find in my Swiza list, the backside tang stamp is A17-52. This could mean that the numbers have unknown factors. A17-52 while the box is without numbering or further identification.
My Swiza D06 black got the tang number A17-098, an extra digit compared to other models with equal amounts of functions. So you see it is not easy to distinguish the tang stamp numbers completely. One indication was
also production year but I do not have 100% confirmation yet. It is very interesting and very fun and adds to the flavor for sure.

In some cases it seems the numbering system on the backside of the blade got unknown meanings for us and it could be for the protection of the brand as mentioned today. It is the number on the
box that is the number that should be used by us for indentification. It is also a very nice feature from Swiza with the production date packaging on the same label and box. The number on the box in my opinion is the only number that we should use and i recommend
to collect the knife and the box. Most collectors i know agree that if you trade a knife in the future it is a big bonus if you have the original box to go with the knife or model.

In some cases it seems blades with a similar tang number can be found on models with different set of functions as mentioned. In some cases
the tang numbers represents a code system and sometimes it seems it distinguish models from each other.

I can add also that my Swiza D06 red got the tang number A17-008 labeled on the box 170523 that should
be the 23 of May 2017 while the black model got A17-098 labeled 170822 that should be 22of August 2017. My Swiza AllBlack D03 with black handle and PVD black functions got the tang number A17-20

On older Swiza knives the A letter with additional number designation sometimes follow the year on the label but absolutely not
always. This you can see on the A17 too.
