The chain tool pin portion of this tool is considered a wear item and is not covered by Park Tool’s warranty. You might want to get a spare pin in case you break one. They’re not expensive. As always, RTFM. We’ve gone years on the same pin on a communal tool. Oddly, Park Tool does not include a spare to make it clear that they consider it a wear item.
