The ash tree is a not a native tree here people have all sort of trees in there backyard you see a lot of olive and lemon growing.I find the wood soft and easy to work all my carveing so far has been done with green wood so no blisters.Here is photo of a spoon I made from my ash tree.That's interesting - is your oz version of ash the same species as ours over here? I've never got on well with it for spoon carving. It always seems rather 'stringy' when green so it difficult to work across the grain and bits tend to tear out. It goes rock hard when it dries so it's no wonder you have blisters on your blisters fishfish
