I believe the gangya (guard/gizmo thingy) is separate, then again I dont own this piece. So I am just taking a guess, though if I remember correctly the owner thinks its separate as well. If I remember correctly this piece is possibly Tausug circa 1900-1930 (though it could be older). These arent exactly very common pieces (this being only the second Ive seen pictures of), and there's quite a bit of speculation of why they were made. Some say Euro influences, others say well bolo influences, Ive always felt that they somewhat look like daos, but then there also the parang possibility, etc...
