I bought a black and a normal 710 and plan to put the black screws on the normal one and vice versa.

These knives are extremely good value for money at least fit and finish wise, haven't used them yet.
I'm not afraid they will fall apart, I have read nothing but good comments on these knives.
So fit and finish is good, although they have some scratching from handling.
Normally I wouldn't except that but for €7 a knife I don't complain.
On the British counterpart of this forum they did do a group buy of these knives and even had a modding contest.
How more knives you buy at the site I linked, the cheaper they get. Maybe a group buy here would be a good idea.
Everytime someone starts a thread about sanrenmu knives some people feel the need to troll and talk about them being knock-offs etc.
It's getting a bit old guys.
@Bigbadboom.
I've read they use the same steel as the Byrd line.
