Etching, Conservation, and when to do nothing?

[Rick]

I have a very similar piece (straight blade) with the exact style of decoration burned onto the rattan wrap ; looks like seagrass waving in the tide doesn't it ?
I know it's hard to resist but leaving it be is the best decision .
Try a Elmer's type glue rather than a resin glue on the wrap ; wipe off the excess with a damp cloth .

It's a beauty just as it is .
