Ive been using the more popular brand and am ordering a new one. I am right handed and use my digger with the right hand. Serrations are available on either side. I suppose going downward on a bigger root with a sawing action, makes sense to have the serrations on the left side, but Ive often used an upward lever like action with some sawing to rip roots etc to which the serrations might be better on the other side. What do you all find the most often used approach? Which would you right handers order? Thanks for your input, CO
