Over decades of collecting, I have always attempted to accumulate as much knowledge as I can across the whole of numismatics.
Unfortunately I have
never been able pick fakes of Chinese Knife Money,

so I have always been tempted to stay away from them,
until I can pick them with confidence. That is a pity, because I have a reasonably extensive collection of Chinese cash coins, covering all dynasties and most Emperors, and I am somewhat more confident with these.
My strong advice is to learn as much as you can numismatically and pricewise about Knife Money, and how to confidently identify fake from genuine
for yourself, before making a purchase. Part of the learning process is to handle and examine them closely and discuss with others, so that you become familiar with them.
I really would like to add an example or two of knife Money to my collection of cash coins.
Basically, I don't trust the Chinese counterfeiters in
any branch of numismatics, and especially their own coins.
