Generally you'd measure it out by weight- some pitch/resin is dense, some is puffy, some is sticky, some like peanut brittle.
But at the end of the day, you have to remember what it is supposed to do, and fabricate your recipe to that.
Hotter climates will demand less beeswax, colder climates more- to cut down on brittleness.
Any particulate inclusion seems to help- I've never used historically accurate horse manure because I didnt want to be heating it up- so I've used bone dust, wood shavings, and sand (sand seems to be a common constituent of the resin used to hold tulwar blades in place)
It doesnt take much to make a mechanical lock, and keep a blade in a hilt. Its funny that today, knives are used less than at perhaps any other time, and they are also more overbuilt than ever before.
It doesnt need to be Full Tang to be Battle Ready
