Sorry Perk I thought everybody had a turn at it, it was meant as a joke if you look at the pattern you'll see there were no straight lines to be had so it better not be cutting straight, But on a serious note if you find your blade wondering chances are you've turned a lot of corners or rounds and we always favour one side over the other so what happens is you wear the teeth of one side of the blade. When you see this happening there is only one thing you can do and that is change your blade. I hope your enjoying the people at the village they really are a helpful bunch just don't be shy.
