To differentiate between the Moro and the Indo/Malay examples here on the forum at least, it avoids confusion to spell the Moro variety as 'Kris' and the Indo variety as 'Keris' .
Moro Krisses are discussed here in the Ethno Forum and Indonesian and Malay keris are discussed in the Warung .
The Moro krisses have a certain brutal efficiency to them; close combat slashing blades; some are indeed lovely .
I collected both; now I pretty much focus only on the Keris .
Be careful; addictive stuff !
