They chipped out real easy at first, but with a few sharpenings this passed and their edge holding ability improved considerably. So not just a problem with the L-N's (in my experience)

Philly, is there any correlation visible between 'time on shelf' after manufacture and brittleness of product. (manufacture/sale dates)
Do chisels left for an extended period between uses exhibit the same problem for instance.
I am wondering if a type of metal fatigue is taking place based on time, possibly initiated in production grinding. It is not unknown for the crystalline structure of an alloy to behave totally different when used or machined in alternate applications.
