Rencong Sizes?

[erikscollectables]

I just read the following here on the forum that was made by Utami:

Rencong is usually ordered by its blade length. Different from Indonesia’s standard measurement, i.e. metric measurement, in ordering rencong, you need to use international measurement. So instead of using “cm”, you need to use “inch”. The length of rencong blade is usually 3 – 10 inchies. The length of blade tells the value and the status of the owner. The longer the blade, the more valuable and can only be possessed by high rank people. For example, a 10-inch blade can only be ordered and possessed by noble or highly respected people.

Is this a confirmed statement?

My rencong with golden crowns is just over 10 inches and I have another big regular rencong that is exactly 10 inches.

Any bigger rencong around?
I think I have seen one that is bigger in a collection (Gayo region) but I am not sure as I did not measure but I am sure it was pretty big...
