Here some blackberries are growing on a hillside. The lower canes tend to be picked over by passing hikers and cyclists, but the blackberries grow all the way up. The best and ripest blackberries are always out of reach. Bring a ladder to reach new heights and the biggest, juiciest blackberry.
Step 1Set Up the Ladder

Extend the ladder to full height, position it underneath the motherload of just-out-of-reach blackberries, and drop it down on top of the canes. It's rare that any canes actually break, and I don't worry much about it because the canes are biennial and the ones with berries are going to die at the end of season. The root of the plant is perennial, and will continue growing new canes over top of the dried, dead ones. In fact, climbing up on the hillside aided by ladder, I've never seen the ground underfoot; this particular hillside might be composed entirely of dead blackberry canes.
I had to put on a sweater, long pants, and sweat me to death :-(
Looks like it works on berries, no bloody arms :-)
