Finally

Finally added this to my tool box. Having the duel heads comes in handy, and I like I can replace ones side if it gets damaged.

Hit things.

It works great when you need a hammer. Ive removed stuck bottom brackets, swapped out cartridge bearings, etc. I do wish it was a bit smaller sometimes, it is a bit overkill for most bike applications.

Hard or soft minor adjustment tool.

Clean up your act and bench with this 2 in one beast.Great for hitting things.

Merry Christmas to me!

Decided up upgrade my 'harbor freight' shop hammer to the park one. As expected, the fit/finish of the park is miles better than that of the harbor freight unit. Function is basically the same (they are hammers after all) but the harbor freight is relegated back into my home/auto tool box and this Park one graces my much more important bike tool kit.

This hammer is great for work on bikes. It has a replaceable mallet head and a solid metal head.

Great hammer

You can pay a lot more for a hammer that isn't near as good. The replaceable plastic head is a huge bonus.

Now to me, if there is one tool that even cheap companies produce its a hammer, and generally the cheap ones work just as well, that being said Park Tool makes the best tools for bikes and i needed the non metal hammer head. Its worked great so far and im sure it will last a lifetime, but thats not to say some of the cheaper ones wont do the same.
