I decided to have a go at making a scythe in the blender render without a tutorial and just a reference image (the fence was done in cycles with a tutorial).
I'm ok with how it came out but I couldn't get the blade to look right for a while and I couldn't figure out why... I needed to bevel some of the edges which made it look 'better' but it still didn't get to what I was going for.
Oh well, practice is practice! :)
