All About Pocket Knives

Gentlemen,

I'm finding myself drawn more and more to these fine knives and still need to learn more before making any rash decisions
dumb question #1
Does the model number you guys refer to designate the o/a length of the knife closed? 10cm,11cm, 12cm mean that's the length of each knife closed??
thanks

The numbers refers to the closed length of knife....

Thanks Camillus. That makes it easier to decide what would be right because you can sort of judge how a knife would look by comparing it to one similar at home.
