Hints on value
It is important to talk to a person that know about them and
not use ebay or the internet as a guide for a value.
To get an idea on the worth then one need to know the history of both brands as best as you can.
The tool evolution need to be up to date and one need to have knowledge on the categories. It is not enough to know that a genuine Swiss Army Knife got an emblem and stamp.
First you need
to identify the knife and category, also get an ok time frame for it. Then check the tang stamp.
After this you need to check for damage or any modifications, condition is important!
If a knife is economy made it is usually lower priced but not always.
If it is limited then it is more worth, we know both companies is a maker and producer
of mass production and thus longer back in history the less production but not always.
Collecting SAKs is fun and some of them got good value, some of the knives sold on the internet give a wrong
value for sure.
What people are collecting?
With Swiss army Knives there are collectors of any sort or category one can think about. So
do not get surprised if a knife is more valuable to some. If you put a collection together then you may get a higher value. If a person makes a collection and can talk about it or show it then there is importance, but only if other people collect the same and that there is a marked.
Retired knives and how long they were produced are important factors.
