Hi Panton, welcome to the forum. Well, i find each of these keris to be interesting in their own right and certainly worthy of collection. The short broad blade is an example of an early buda style keris sometimes called keris picit, though yours is not an ancient one it still appears to have good age and some interesting talismanic markings. The indentations along the blade are supposedly placed there by the empus fingertips while the blade is still hot.

They all need a good cleaning and restaining and the spacers (mendaks) are easy enough to replace. Depending upon where you live having sheath made for them will be your hardest task. Thanks for giving them a home.
