We use this tool every day in the shop, multiple times per day. After about 2 years, we've never had a pin break. Metal shavings do collect around pin from chains, and needs to be cleaned off after about 20 chains or so.

Park Chain Tool

Ergonomics, Easy to Use
Pin broke after 2nd use, Weak
Best Uses:
Great ergonomics but woefully inadequate durability. Pin broke after second use, could not replace.
