Tom,
Thought id give you my 2p worth, as some have said the Ayrtek name and logo fails to hit you properly and as suggested white and silver trim may be a better stand out option but to be honest that's only a slight tweak etc. With regards to the shape i feel the sticker on the face of the blade side would look better square on the left side and slightly shaped on the right. As it stands in my opinion you can see the wood either side of the sticker which doesn't work for me.
On the back again I'm not 100% on the split either side of the spine, I'm not sure it work properly but as yet I'm not clear on why it doesnt look right to me. Just a few honest thoughts but hey not far off.
