How to make pitch

Making pitch

I want to learn how to make pitch to be used as glue to hold on knife handles. I have no idea where to begin. Can you help?

Also, can you tell me something about the 'qualities' of pitch please.

Is it brittle, meaning would it fail as a fixitive, or is it flexable and tough and how does it perform as a fixitive to wood, metal and bone?

I don't really want to use modern fixatives. I would much rather learn the 'old ways'. Can anyone recommend a tutorial or a good book?
Some glues and resins go brittle and fail after time (several years), does pitch do the same?

Thanks,

Bear
