Suspect that the knife is an Imperial Cutlery Bowie knife from the 1950's. The handle looks like bone, but is plastic. The knife used to sell in a display case with their folding knives for about $1-$2. Can't really tell because of the dirt, but the large pins on the handle match the Imperial. Solingen and Westenhome(IXL) bowies had much smaller pins. Check google or ebay for pics. The axe head looks very recent also.
