The 1/6 Mononofu swords are made of real metal and not painted, the edges are blunt. And the swords have an etched hamon. (A hamon is the wavy pattern near the blades edge). It's the only company that does Hamon on Katana blades, that I know of. The Tsuku (handle) of the swords of the Mononofu series can be slide off and they have an engraved signature of the 'sword smith name'. The tsuku fits snugly to the Nakago (tang) and wouldn't fall off so as to speak. The Tsuba (guard) is also detachable.
The blade fits well into the scabbard as well (Saya). So you can do all those sword drawing poses.
As for the Sageo (Cords) if you untie it from its knot (Musubi), You will find that its not done with 1 long strip of ribbon but instead two strips of ribbon. One of then is lightly gluded to the Saya (Scabbard). The sageo in real life is just one long cord. So if you are planning to remove the knots, bear in mind this point. I un-did my Mononofu Katana musubi.
They are going quite cheap on ebay, at one point of time J-List was selling the whole set of the Shinsengumi Mononofu swords (The series shown in the photos by Bantar) for I think US 45? you can buy individual swords from Hong Kong Ebay sellers. Usually going for less than US 10 bucks each.
The Mononofu series katanas are -the- best 1/6 katana in non-tachi mounts avaliable. I think they do a few in tachi-mounts (where the edge is worn downwards like in the Takeda Shingen swords) but its in a different series. So if you are planning of bashing some Japanese swords go for it. You won't regret it.
I just read cryoguns post, the mononofu sword I had is the one shown in the last photo by Bantar. I can't say much about the rest of the swords in the series though. But at least that one fits well.
By the way Mononofu, translates as 'Serving Object' (i.e retainer) it is another way of calling a 'Samurai'
