The Park Tool ST-3 is a reliable 3-way socket wrench for bike enthusiasts. It's well-made from durable steel and has a solid feel. The 3 sizes (8mm, 9mm, 10mm) cover most common bolts, so you don't need multiple tools. It fits comfortably in hand and applies torque effectively. While it's simple and practical, the design could be more stylish. Overall, it's a good socket wrench, but not perfect. 4 stars.

Like all Park tools, this is well suited for working on bicycles and covers most of the common nut and bolt sizes you will find on both modern and vintage bicycles.With this tool plus a 3-way hex key, you will be able to work on almost all bicycle fasteners except for certain crank bolts.The socket sizes on this tool are also very common for non-bicycle applications, so it's worth getting one of these even if you don't work on bicycles.

I replaced an off brand tool with this Park model and was immediately pleased upon first use. The old tool served me well and is still a usable spare. The Park tool is bigger with longer shafts, allowing easier access to some bolts. Also, there is less torque on my hands and wrists. The chrome finish is good quality.

I have the Park Tool AWS-3 3-Way Hex Wrench and have been very happy with it so I knew this would also be of the same quality and I was right. This tool saves time when having to use the same size sockets all the time. It's simple yet effective. I don't only use this for my bikes, I keep this very handy for around the house too. I constantly find myself having to use either an 8mm, 9mm or 10mm socket. I've always been happy with Park Tool quality but sometimes some of their tools are too expensive for me, the home mechanic, but this is very affordable.

Good feel in the hand, easy to apply torque because you can use your whole hand, not just fingers, 3 convenient sizes in the hand when you are reaching an awkward nut and are not sure of size.I have several Park products and they all make my tinkering easier and more fun. I am highly unskilled and just want to get back on the road as soon as possible. This tool helps.

Excellent little wrench for bike and general auto motive repairs. As with anything made by Park Tool, the quality is superb. The design is superior to any type of screwdriver style nut remover, as the handle gives you the ability to apply ample amounts of torque.Highly recommended.

I've only owned this tool for a month, and it is already my most used tool. It's great to have 3 of the most used socket sizes on my hand at once. I save a lot of time not having to search through my disorganized collection of 1/4" sockets.I have found myself using it on many non bicycle related tasks, such as ceiling fans and file cabinets. This is a great tool to have, even if you're not a bicycle mechanic.
