I always have a problem opening Klner jars, the type with a glass lid.
Releasing the vacuum can be a PITA, the problem is one can easily chip
the lid or bottle rim. Has anyone found an easy fool proof way of
opening them?

I don't use Kilner jars but can appreciate your problem. Just a couple
of thoughts.
1. Lightly grease the rims before closing.
2. There is a plastic tool with a strap attached that you fit around
the lid. Tighten with the handle and pressure from your hand should
release the air pressure. I nearly bought one some time ago. for
opening new jars, for my grip is not as strong as it used to be.
