I found these new pruners a couple of years ago made by Felco. They have a rotating handle which makes it much easier on my hand when pruning. I love Felcos because they come completely apart for cleaning and sharpening. I have had one pair since my first year of school, 2001, and love them. They stay sharp and clean easily! This particular pair is Model 7. If you are left-handed, then you will want Model 10.

If you go to their website, they also have tips on maintenance for their pruners. I love them. They are the only ones I use.
