That scissors spring remainds me about Spirit scissors what also has samekind spring.
Here's mine. Agree that it's mostly good, but the scissors are lacking.
I have the same one and agree the scissors are lacking, but I do like the combo tool and the beefier blade compared to similar size SAKs
My experience with the scissors is that they are lacking springiness to press the blades together at the cutting point. (snipp...)
It seems likely to me that there is some variation between individual scissors even within the same models. J2000E certainly seems to have a better Ruike scissor than I do, and a worse Victorinox SAK one than the one I tried. (Ruike got some feedback about the scissors at the introduction so I assume they have improved those in the years between). And the scissors on my Vic Spirit seems to be a particularly bad one as I don't think Victorinox would be ok selling scissors with such lack of performance - it just seems the pin at the fulcrum is too loose. So not sure if one can actually conclude much as it seems to be inconsistent performance even within the same models. I will say this for the Ruike though - the knifes on my two Ruike models are very good, and those will outperform any SAK I have. Performance wise I think the knife is the highlight of the Ruike.
