This may have been a fluke, because all of my other Park Tools have performed well including my dedicated chain breaker, but I attempted to use the chain tool once on my I-Beam and the pin broke. It was not the same material as the pin in my home use tool. I was lucky in that it happened at home, I only grabbed it because it was handy.
I considered replacing the pin with the type from the CT series if they fit, but the IB I had was a chunkier model than the 3 and instead I moved on to smaller tools from Lezyne and Topeak.
