Park's Master Chain Tool is designed specifically to work with the tight tolerances and narrow profiles of 10, and 11-speed chains and most high-quality derailleur chains. It uses an integrated link pocket to ensure precise alignment and also features perfectly contoured, cushioned handles for comfort and ease of use. (The CT-4.2 is not compatible with Wipperman chains.)

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.
Great ergonomics but woefully inadequate durability. Pin broke after second use, could not replace.
