That spatula has held up surprisingly well, I think not due to the Olive Oil which I rubbed onto the surface once which would have been washed off after 2-3 washes, but more thanks to the durability of the timber used.
I think a spatula made from a less durable timber would not have lasted 10 years of dishwasher treatment. Even if it was only washed once a week, thats 500 washes in the dishwasher, but most weeks it would be washed a few times.
Here is a pic of said spatula, as you can see, the colour has faded quite dramatically, but the timber is still sound. It was originally a rich Mahogany colour with ribbon figure.
