Ivory tango says translation and info

[Mjs22]

I purchased this elephant ivory tanto in England about 25 years ago. I was wondering if anyone can translate the saya mei(???). And if anyone has some info or observations they would like to share.

 Thanks

Maybe 玉雪刀 (Carved by Gyokusetsu). 

 

Gyokusetsu would be the artist's "art name".

Just bear in mind that the blades in these export-type mounts are usually low quality, made for the Meiji export trade. Carving on this one isn't terrible, nicer than most. Blade looks like a shortened waki or something, but maybe traditionally made.
Can't tell if this is ivory or bone. Very often they are bone.

You usually have black 'dots' on bone but not on ivory

Thanks to both Brian and kissakai. I’m 95% confident that it is ivory as I imported it from England and had to jump through hoops to get it to the states. 
i never held out that the blade was anything more then for the export market. I was interested in trying to remove the tsuka to check the tang but I believe it is not meant to be removed. No mekugi except in the very bottom that is set vertically not perpendicular. Any ideas
