not sure about autoharp. On a piano it is short and sloppy. but it works.

Great tool works really well

You need to check the head size of your tuning pins. This wrench works on 1/4" piano tuning pins. My guess is your autoharp uses 3/16" tuning pins which I use on my zithers. I had to return this wrench because it was too big.

The one I bought two years ago was recognizably similar to the one in the image

It did a good job tuning the strings to themselves on my piano which had a some strings that were out of whack. It easily tuned the strings that had dropped out of tune and if I got a little sharp it allowed me to loosen the string and try it again. The Square end fit tightly on the square pegs and did not have any play in it. I have yet to tune my piano with a tuner because it wasn't that far out and I didn't have that much time on the day I got it so I can't comment on how durable it is in the long run yet...the fake wood (plastic) handle didn't feel like it was going to break at any point. It has been worth the money I paid for it just getting it back in tune with itself. I will update my review if I find the quality to be poor when I redo the whole piano to a tuner but otherwise you can assume it still works good. At this time I'm happy, -M-

Granted this is the cheapest one offered by Tomtop, so no complaints. If I had it to do over, I would have spent a bit more for a wrench with a longer handle, a tighter fit, and a star (asterisk) shaped hole. It's a little harder to get the wrench at the correct angle with only 4 contact surfaces. Still, it works fine.

This has a metal socket and neck, with a plastic handle. Simply does what it is supposed to do. When tuning a piano, a lot of the difficulty comes in how tight/old the pegs are, not on how expensive the wrench is. I was able to fine tune an old upright with no problem, and also take strings completely off with little effort, but again, this will vary by piano.

Works great, but I wish it were just slightly longer to give more torque. I have a very old piano and have to micro-tap this thing with one hand while turning it with the other to get small adjustments of around 3-5 cents. I'm sure with another 1.5-2 inches extra on the handle I could get it down to 1 cent. I'm tempted to take it to the saw and weld it onto a bigger rod.

I was very apprehensive about trying to tune my Hinze piano myself. I've heard intimidating stories (from professional tuners) of how you should always call a professional, because this is just too big of a job for a mere piano player. But, recently the piano fell so far out of tune as to be unplayable and I was left with the choice of spending significant money on a tuning job, or doing it myself. So, I ordered this wrench (because it looked stronger than some of the others), and gave it a go. Armed with a chromatic tuner (which I already had) and the wrench, I started with middle C (which was way off) and had it on pitch in no time. The wrench worked fine. It seems sturdy. However, it was much smaller than I expected. It takes a lot of strength to tighten the strings and a little more leverage would have helped me control the adjustment better. That's why I give it only 4 stars. Otherwise, I'm quite happy with the purchase. Tuning is easy - tuning really well is not. It takes time to tune over 200 strings, and as the overall tension changes, I have had to revisit some of the strings I've already tuned. My tuner doesn't pick up the low frequencies well, so I'm tuning the lowest strings by ear which is much more difficult. Also, I can't really stretch the octaves across all 88 keys so that they sound perfect. I'll probably have the piano professionally tuned at some point, but I'm very happy
