Welcome Shawfan. I agree with Rick, new work. The wood of the wrongko and hilt is beautiful. The kinatah (gold part) on the blade looks a little rough, but that might just be because of the way you photographed it in the bright sun. But it almost looks painted on.
I wouldn't think that a contemporary keris like this one holds all that much mystical power, so you can probably assure your wife that it's safe to have around.
