This tool is a 2 in one which means it enable riders to remove ISIS or Cotterless crank arms. The tool has a large foot at the base of the extractor for ISIS and remove foot for Cotterless use. This is needed with ISIS cranks because a standard crank arm removal tool is not fully compatible with ISIS crank arms and this tool will work with both types of cranks.
Great tool, Instructions could be better

As a new unicyclist in training I found I had bent up my pedals and cranks. This tool certainly did the job quite well, but I found the instructions assumed the end user was already experienced in pulling off cranks and merely showed the differences in configurations for the different types of cranks (Isis or cotterless) rather than detailed instructions. There is also no mention to remove the disk if you're not using it on Isis cranks. Yes I want instructions for dummys (and a video would have been nice too)
Ultimately, with some research, I was able to figure it out and in short order had repaired my problem. Obviously, everyone with a unicycle should get one.
Does what it's supposed to do

Got this along with new cranks when I stripped a crank. It does what it's supposed to do.
