This tool works. But not in every situation. There are times when the female "bolt" installs more than flush with the male "nut." This makes seating the tool very tricky, especially if the chainring bolts are at all frozen in place. As with a previous reviewer, I too have lost some knuckle skin extracting stubborn bolts with this tool.

I wish there were a more fool-proof solution, but until then, grease your chainring bolts and buy this tool!

I expected better quality from a company like Park Tool. This tool is made out of flimsy sheet metal, doesn't even appear to be hardened. That said it does get the job done and is handy to have in the tool box. It definitely beats using a screwdriver.

          Sold a frame which included the cranks I tried to remove my chain rings prior to sell with no luck. Ended up giving my chain ring with my single ring bolts with sell. Wish I had the the chain ring tool!

              I've had this for a couple years now and have used it on my mountain, fixed gear and cyclocross bikes without any issues. No bending, the finish remains intact and it gives more leverage than a screwdriver ever did for me. Thanks again, Park Tool!

                A screwdriver would work fine. If you're removing ten chain ring nuts a year you don't need this. If you disassemble your chain rings after every ride it's worth its price. Super simple and effective. The tab that fits into the hole in the chain ring bolt really helps keep it centered. I like that it's light enough not to bother me in my apron but it isn't confidence inspiring on tough bolts. That said, I haven't bent it yet either.

                    Well worth the price if you need to change out chain rings. My cross bike get 36/46 up front during the race season, and then gets 50/34 as my gravel/rough road/winter bike the rest of the year. I have mangled soft bolts with a screw driver. This tool is less than a new set of bolts, and gets the job done.
