Small knife collection, any info is appreciated

I was told today that I shouldn't carry it as it's valuable. Is it?

Kershaw S1670OR ? It could be, but it is hard to evaluate. It is discontinued. The knife technically isn't very valuable, but maybe the burnt orange model is valuable to collectors.

Just because a knife has value, it doesn't mean you should use it. Knives are tools. And Kai can fix it if it breaks.

Anyone know what these are worth? Should I lock them up/sell them/start carrying them again?

Can you post the information on the blades so the models can be more easily seen?

They are not cheap knives, but they are all used and worth using.

What are the details on the Elishewitz design? It says first production run. That could be something.
