Somewhat unhappy built ...

I collect knives and had such a design not with ring opening.
Since it is made in China, I suspect that the Chinese have smaller fingers than
Europeans - the forefinger you get a man in any case only with bruising
through the opening. Can therefore "only" hold normal, or you look at it in order and puts the
little finger through. The catch is not as clean as other manufactured knives
with the same level of protection (eg CRKT). If you are not careful and accurately controlled, may well
the knife fold unintentionally. The lever to open the blade is in my opinion also on the small side and
might differ slightly placed.
In short: Larger "hole" and a slightly better processing and three stars would become 5.
