looking to buy a new pair of hedge shears soon. i have all the gas hedge trimmers looking to buy a decent lightweight hedge shears. i do about 3 days of pruning/shaping, so looking for something lightweight to reduce the wear on the arms. looking at Bahco's right now' price isnt a factor but would like to stay under $100. needing something with replaceable blades. i been using coronas in the past years but they only seem to last a season. any suggestions.?
