Tridacna hilted Keris choices

[Gavin Nugent]

Good people,

I have another two keris added to my growing modest collection today.
Both appear to be original and untouched, showing nice honest patina to the hilts, mendak, blades and scabbards. Both have Tridacna hilts with beautiful swirl patterns throughout and they feel so very comfortable and pleasing when both held and viewed, really a total feeling of comfort.
My question really is one of personal choice but I wish to hear words of wisdom from those more familiar with such choices. To touch or not to touch.
By touch I mean, change from this long standing static condition to a rejuvenated condition, oil the scabbards, clean the blades and polish the mendaks. One Mendak has been squashed but I think with care this will 'pop' right out.
Your direction is sought.

thanks

Gav
