More of an educated guess than neither option really! I couldn't think of any other (modern) discipline that would require a hammer on the kit. I got drawn to the photo thinking the bone nibblers were dental forceps, then realised they weren't (at the same time as noticing the hammer!). Great shot.
No probls. I need a 365 boost at the moment (having a bit of a slump!) and I think a themed series is the way to go. I just need to think of a theme! I'd love to see a bassoon-themed week sometime (such a fabulous instrument).
