Edge & corner damage

[Farrell]

Hi Clark. Thanks for the info. Could you expand/clarify two items for me?

"I like to do this (cut through the new and old veneers at the same time) by
hammering a break-off blade ..."

What is a break-off blade?

"Hammer veneering with hide glue works best"

I have no idea what "hammer veneering" is. What is that?

Do you have a suggested reference text for the ABCs of veneering & veneer
repairs?
