I have 2 vtg razors originally scaled with Ebony. Both appear as the bare naked wood itself, without finish or sealer.

Given the density of this wood and its ability to take a high polish, apparently the craftsmen a century ago felt no need to seal. Indeed, both samples show no sign of warping, rot or any water damage at all.

Quite an interesting wood. Just the lightest sanding of a small splinter and the sawdust is like charcoal soot.

I wonder if you modern users of Ebony are sealing/not sealing ?
