Basically, it's kind of hit or miss with the sword line - not sure how much of my info is outdated now...
The sabers are good with good comments on the 1796 (not quite exact in the handling, but still very good) and the 1830 - this is secondhand. The Viking swords are considered good, but there are better ones (like the Kris Cutlery or Albion Squire line) for significantly less - I've not handled the Albion Squire Viking but all comments seem to be good. I've heard the baskethilts are unwieldy but have not handled them personally. The bastard sword is a tad on the heavy side and there have been a few mentions of failures with the handle construction.
Japanese line: can't comment on the new stuff. Generally in the upper weights, but still quite useable. The O-katana is ridiculous.
Chinese War Sword: meh. Not particularly great, came with a sort of convex edge that's not honed properly. Handles alright, but the handle wrap isn't particularly tight. Guard and pommel seem to be blued, and it's rubbing off just from leaning against the wall...
