Re: WW II era fighting knife and machete
Ken, the KaBar has no collector value given the overall condition and the blade being ground back like that. Huge numbers were made and they are valuable only in mint condition or provenanced to particular individuals.
The machete is nice- use oil and 000 steel wool to gently remove the rust. With scabbard it's worth $125 or so the right collector given my understanding of the current market.
