How to write a novel?

[tiornys]

Question: I have an idea for a minor antagonist to be armed with a club with the stone on the end being a chunk of sharpened diamond. Could this work as a weapon, or is diamond to brittle to hit someone with?

I'm not a student of material sciences, but a quick google search suggests that diamond is too brittle for large pieces of it to last for any amount of time as a weapon, especially in a club/mace/axe style setting (I found multiple comments talking about how you could shatter diamond with an ordinary tool hammer). You'd be better off with some diamond edges for slashing (similar to aztec-era obsidian swords).

A bit of magic could potentially fix that, of course.
