Keris hilts with raised curved backbones

[Loedjoe]

This has been a fruitful thread - many thanks to all those who have contributed to it.

There remains the question - how do we refer to these hilts?

If hunchback is perhaps unacceptable, how about humpback? (And our descriptions could give a reference to this thread.) To refer to them as Richard III or Notre Dame or ... hilts would be a bit misleading.
