This is real!Syaoran's sword from Tsubasa Reservoir Chronicle. It is modeled after Li Syaoran's sword from Card Captor Sakura and is very similar in details, but pewter in color instead of green.
The sword is made mostly of wood and honed to an edge with a belt sander. The raised detailing is built with Super Sculpey and Paperclay, with glass marble accents. The long tassel is made with cording and features glass and wooden beads, a large glass marble, a hand-tied square knot chain and Chinese lover's knot.
Made entirely by me, =Bekalou
