I would love to have a Shake’n fork. I used to think they were pretty silly, but then I had a bad case of bilateral tendonitis in both elbows. Stall cleaning was very painful. Now I am battling cancer and am so weak from chemo that I can barely shake a fork. Nope, not sill at all now

Is my fork of choice. I have had one for 6-8 years cleaning up daily after 8 horses. They are not stalled but have 2 run in sheds (18x36 and 12x36) which they consider their bathrooms so lots of cleaning up every day. They will come in from the hay feeder and sometimes from the pasture to use their “indoor plumbing”. I guess they are worried I won’t get enough exercise if they are cleaner.
I have had to tighten the nuts on the handle bracket and have bent some times on the lovely frozen apples but they bend right back. Not real heavy and well balanced.
