When you're ordering tines/blades, it's important to know which side is right and which side is left. So which is which?

The easiest way to help determine right from left is by holding a tine/blade in your palm. With the bolt holes facing toward you, look at which way the cutting edge is facing. If it curves to the right, it's a right hand blade. If it curves to the left, it is a left hand blade.
