Vintage Carved Wood Spear? Blow Dart?

Description

This estate find was part of a collection including animal hide shields, spears and carved bone blow dart gun.
I'm not sure if it is a spear or a large blow dart.  It appears to be hand carved with a burned wood design.  It
measures 17 1/2" long.  One end is worn off as can be seen.
I have another one listed also.
Item sold as is.
