Note, my above post was not meant in a Negative way towards the regular or even the $25-50.00 swords.
I have doen a lot of checking and it appears that there is 1 or 2 companies importing these to the states. Sunpointblvd.com aka Handmadeswords both list on ebay and Sunpoint.com has an online store as well. If you do a search for Furibushido, Masahiro, Ryumon on Yahoo it leads back to Handmadeswords.com with subcatagories going everywhere.
My thinking is that prefect blades are paired with the best Saya, Tsuba and grip with the best clothe case, box and carry the Masahiro or other such name.
Blade that have a few blems (cosmetic) are assembled with Saya's with the same, lower quality Tsuba and so on and marketed in generic boxes.
Blades that fail to past due to structurial defected are tossed in a pile and recycled in the next load of carbon steel.
I kind get the feeling that one large importer is bringing in a container and distributing these...Possibly Sunpointblvd in the importer, I don't really know.
I did see that even Oni Forge has a bunch of second and blems that is are listed with anything for poorly polished blades, loose tsuba, rattling grips, loose wrapping but nothing where safety would be a consern...Just cosmetics.
I did question Handmadesword on eBay quite intensely and was assured that "All His Swords" where considered safe for cutting and practise.
I also had another once over with the $25.00 Masahiro I bought and holding in up towards the light and looking the lenght of the blade the blood groove/fulller is a little wavy an irregular compared to others blades I have here.....Maybe that is why this blade is paired with a Saya that is not prefect and was packaged in a generic box even though it still had a Masahiro part #.
I doubt the wazy forging in the fuller would in any way weaken the blade to a point where is could be deemed Un Safe but would most likely not be suitable to be sold as a 1st grade Masahiro blade.
