I use a pair of large dog nail trimmers. I like the blunt ends, so there is no punctured fruit when they are in clusters. The curved blades help to get in tight spaces, once on the stem, they seem to slide around it easily. They are spring loaded, which helps a lot, but the lock to keep them closed can get in the way. I may remove it. I am testing them this year to see how they work out, and so far, I like them.
