I then set about dry-brushing it with Games Workshop Golden Griffon Drybrush paint. Not only is it specifically designed for drybrushing it was also exactly the shade of gold I wanted. Result!
Next I masked off the crossguard and sprayed the blade with Halfords' Chrome enamel spray. On my Bat'leth I used Plasticote chrome which really looked like metal (to the extent that some folk, even on close inspection, thought that it was metal!). However I had a nightmare with it because it doesn't really appear to harden, meaning that you really shouldn't handle it - not good enough for a cosplay prop. So I thought I'd try out the Halfords stuff and it appears pretty good. It's not going to fool anyone up close but that's not really a deal breaker.
Next was the hilt. Now this was a nightmare simply because there really is no reference for it. Every shot of the damned thing is covered up by the character's hands. The only clear shot of it is in the plans where it's a sort of strawberry icecream pink and I'm really not convinced that's the colour it's supposed to be. You can see a glimpse of it in one of the original ref pics I had and although it's only a coupld of pixels, it appears to be a sort of grey-brown:
In the end I went for a red-brown. It was richer and slightly darker than the ref appeared but I felt that the red complimented the hearts and went with the gold better.
Finally I painted a dark brown into the grooves of the hilt and varnished over it to afford it a bit of protection from handling.
I then mixed up a hot pink using Tamiya gloss red, yellow and white and painted in the 'heart' inlays on the blade. The pink tip on the pommel was a bit of artistic license but I felt it balanced out the pink on the blade.
The finished sword can be seen in the first post.
