I want to purchase some good hedge shears to trim boxwood - smaller border hedges, rounded forms - I want to be able to do a fine-clipped formal look. I am looking at ARS and Okatsune brands - about a 6-7" blade. Considering the lightweight, thin blades - the topiary/shrub type. I am not sure of the exact size I need, if I need more than one pair of shears - the long handled ones and short handled ones for fine tuning. Which brand is best? I am not well versed in trimming, though I am an experienced gardener. Would appreciate any assistance in helping me make a decision. Thank you.....
