Park Tool  AWS-8 3-way Ball-end Hex Wrench

Another super useful item for your toolkit. This version has rounded tips which makes for easier insertion at odd angles. I almost never need stand alone 4-5-6 mm Allen keys, as these do the trick nicely. I just upgraded from the cheaper Park version, which I gave to my son for a starter toolkit, after getting decades of use from it.

Perfect tool - have used this tool in previous jobs. The ball-end means you can tighten and loosen the screws from a slight angle. Comfortable to use.

Well made and works for common bike allen wrench needs. I use it for seat adjustments, and it works perfectly.

This tool is so good that my auto mechanic son kept it for work. Had to buy another one!

This is a really convenient tool. You can almost build a whole bike with this:)

I like using this wrench. It's convenient to use this one tool to make adjustments on my bike and not have to keep track of three separate wrenches.

Surprisingly easier to use than Allen wrenches. Design makes it easy to generate good torque and also easy to loosen tight through-axles.

Nice having 3 sizes in your hand that can fit most bolts,and their locations,on my touring bike

It's a nice tool, nice quality it fits in the palm, and Park has the sizes right
