I own three of the Boker Magnums (China). A Medium Stockman, a large 4 blade Congress, and a Copperhead.
They are all pretty well built. The Stockman and the Congress I don't carry much. The Stockman's springs could be a little stronger, and the Congress is pretty hefty, but the Copperhead is pretty sweet. The Copperhead is on par with most standard Case knives as far as initial F&F goes. The slightly strong pull is just right IMO for blades without 1/2 stops, right between case and GEC. The scales thmselves feel and look a little less refined than our domestics or German built, but there are no gaps, the springs are flush, the blades are sharp and look better than the $7.50 (to my door) that I paid for it says they should. Time will tell just how big of a bargain (or not) these turn out to be, but IMO for $7-&10 you reallly can't go wrong.
I have a few Rough Riders as well and I feel like the Boker are just a little better in the F&F department, and the blades are finished/ground just a little better.
