i got this tool from Taobao. I used it on the left crank of my cheap 20 year old single-speed cruiser; and it worked great.
But then I went to work on the right crank. But the right crank is super dupper tight. I ended up stripping the inside thread of the black part of this tool.
I cannot get Park Tool around here. But the LBS has a $10 tool that looks similar to my ruined one.
Is it normal to bust up these tools?
or is the old crank really so siezed up that it may be unremovable?
