Sepuh or ipuh in a keris

[oracle_2010]

Hi David & Alan, thank you for your explanation.
By the way, the keris Minang pictured here is actually small one (the blade is less than 25 cm in length) and it got sepuhan on the tip part of the blade.

I have seen the previous thread which discuss the small keris or called keris selit in the Malay culture which is functioned as dressing companion. But judging from the sepuhan exist on the keris that I've shown you, is it possible that these small keris may have practical function (eg: as a weapon)?

I also attached picture of a tombak from Palembang with sepuhan only on the tip part.
