Nicely done Tim! Spot on as always
I was puzzled by these, but felt as well that they were not Native American. Most of the steel examples of Native American seem to have fully formed socket and similar leaf type head with central ridge, typically Spanish colonial provenance.
Kronckew, it is most interesting on your mention of Blackfoot ancestry. During travels through the plains last summer, I became very interested in Native American weapons, and it seems at one time or another we were always passing through, or often encamped at, various tribal lands.
I wanted to let you know that the Blackfoot confederation were considered one of the most dominant tribal factions, and often most feared by both White and other tribes with whom they were at odds. These warriors did indeed use the lance, however thier lance heads were typically bone, with a concave cross section ("Mystic Warriors of the Plains", Thomas E. Mails, N.Y.1972, p.447) ; or of bluestone, with a rather flat cross section. These bluestone heads were outstandingly made, and quite heavy, often serving as an effective club (op.cit.p444). The war lances shafts were often highly decorated and shorter than the undecorated hunting lance shafts. It is said the shorter the shaft, the greater the courage of the warrior.
While this topic typically finds limited interest here, I was pleased you brought it up with your post and note, and couldnt resist the temptation to share some information on this extremely important plains tribe.
All the best,
Jim
