Hi, can anybody tell me what kind of knife this is.
It was used in a double murder in Sweden 2004.
How old could it be?
Original or copy?
My private murder investigation on the case:

you see lenn,
for anyone to identify a knife correctly,
there first must be a maker's or manufacturer's stamp (usually found on the tang).
if there aren't such markings,
then it would be like a trying to precisely id a gun's origins without serial numbers.
i concur with others here that the pictured "balisong knife"
is a generic copy.
i have observed the word "stainless steel" stamped on its blade,
which is not uncommon for knives.
to be like that found on cheap copies
also the rivet pins are not stainless steel (which high end models use)
but rather appear to be nickle plated?
most "balisong knives" with these stated physical characteristics
come from the far east.
notably either taiwan but mostly china.
previously in the early years it was predominantly japanese and to a small extend korean made.
i would suggest you look up a jeff imada's 1986 classic book
The Advanced Balisong Manual.

because somewhere in there lies a sort of catalog of balisongs from the era.
