The blade itself is a pen tool shape with alpha channel and
Filters / Rendering filters / ?lighteffect? (not lens flare, the other one. Spotlight thingy.)
The hilt is also alpha channeld + Renderfiltered.
The part between is also alpha channeld + Renderfiltered.
Details are shapes with Bevel/Emboss layerstyle also added Bevel/Emboss layerstyle to the other parts to get a more 3d look.
Optionaly i used some texture overlays (wood, brushed metal).
