Getting back to the original question regarding "What knives were really carried?",.... I thought an invoice list of trade goods going west to the 1831 fur trappers rendezvous might be of interest. 
I'm sure many fur trappers replaced their personal knives that were either, lost, stolen, broken, and etc., from the traders offering such items at rendezvous.
I hope you find the following as interesting as I do.
