It looks Japanese, a Kama Yari spear. They come with these side spikes, facing forward or to the rear... The construction of the haft mounting looks traditional. As noted, It could have been cut down by someone for shipping convenience. Common for spears. Many have the joint converted so they shaft can be re-joined for display, tho it's not a strong as the original.
My Yari point is a Fukuro Yari point, pocketed for easier re-hafting in case it gets broken, rather than the long tang most have that requires it to fit a socket drilled into the haft, then reinforced with metal bands, and/or other bindings. It also has been shortened.
