I got one of those samurai too, he's quite nice and the parts seem quite usefull.
Seeing how my customisation options are limited to the figures since I never managed to take other clickies apart, the simple red torso makes him very handy and versatile to me.
As for the sword, I'd like to point out that one of those holster thingies like on the viking of the figures can be put on the spot of the quiver, allowing this fellow to wear his katana on his back. It would mean he cant have the quiver, but I'd gues an archer might better have a dagger than a katana as a sidearm anyways.
