Around the edges of my veggie garden plot there's tall grass growing and it's right up against and in between the chicken wire of the plot (I have chicken wire around the plot to protect the veggies from animals). So I don't want to use a weed eater and the clippers I've used don't do a good job. I'm not sure if they just weren't designed to clip grass or if it's because they're old and possibly dull. I need to get a new pair and was hoping for some recommendations?
