The Cutter Doc Y-Key includes 4, 5, and 6mm hex keys to help you fix your derailleur, tighten your headset, or snug down your pedal and keep from walking home. Cutter’s three-prong design gives you way more leverage then a standard L-style wrench, so that half-rust, super-stuck bolt doesn’t stand a chance.

Nice Travel Tool

This was a great tool to have on my recent trip to Spain and France. It came in handy for tightening up the parts that the substandard French mechanics failed to. It was also nice for removing pedals from one rental bike to the next. It's relatively small and packs easily.

Awesome convenient tool

This tool is one of my go too tools for quick adjustments on the bike. This gives you the best of both ends of the traditional L-shaped allen/hex wrench. It has extension, to reach those bolts tucked behind other components, and has torque power to tighten without having to pull the tool out due to having limited rotation room.

With some bolts, it performs worse, such as disc brake calipers, due to the spokes getting in the way, but for a vast majority of other bolts, I find it does a faster job.

Great tool

I bought this one and the Park 3-way at the same time and I like the way the Cutter Y-Key feels over the Park tool. Both are great tools, but I keep grabbing for this one.

Cutter Doc Y-Key is a must have...

The Cutter Doc Y-Key is a great tool at a ridiculous price and has been my most used bike tool for the last couple years. The design provides great grip and leverage, which is especially handy for loosening stubborn bolts and even pedals. It's a nice size as it fits easily into any pack and with three common Hex sizes, has saved the day more than once. The Cutter Doc Y-Key is a clear cut winner - 5 Stars.

It was free, not much to say...

It works.
Due to its shape its hard to use on a lot things. (i.e. attatching bottle cages, etc.)
Like I said it was free...

Recommended basic tool

Good to chuck in the car, tool box or jersey, strong for higher torque application and quick, just handy to have when tweaking the bike or going over it.

Killer Grip

The Cutter Doc Y-Key has a killer grip. The rubber body makes it easy to hold. The sides are concaved, not convexed, so it fits nicely in your palm.

Great sized tool for tinkering around at home. Not one that i would take on the trails, but i've used it a lot around the casa, fits in the hand well, does the work that needs doin.

You're the tool

Definitely a must have. Even if you bike-stand-less and don't know anything about bike tools - you'll look and feel like a pro mechanic when wielding this handy tool. In fact, you may just want to carry it in your pocket at work - you know, just to look cool.
