Hi Wendy and welcome to the forum, I believe this a Rentcong (Rencong) not a bade bade. This style of hilt is calle hulu puntung (this is the Indonsian name if I am right with the Aceh term being Hulu Geurepong and hulu gerepung being the Gayo term, if I am wrong someone please correct me). These are found throughout Indonesia and carry as strong a significance to the people there as the keris in other places. I would guess this one is from Aceh based on the floral motif on the sheath. I will try to look up the name of that motif when I am home tomorrow night
You may want to look at this thread started by Utami for some good background on these.
