What is this Japanese tool used for? Any information on it whatsoever?

[Sazabi]

I'll take more pictures of it later, but it's the silver tool on the righthand side of the picture; I do know it's a Japanese-made tool, and that it has a nail file and nail cleaner, what appears to be a recurved blade, and a hollow tube tool on the backside.  Beyond that, I know it has a sheath and not much else, aside from the fact that it's shiny.   Help?

Looks like a tool to de-core fruit  that or a ninja assassin's blow pipe

Its one of the  tools carried by manicurist & pedicurist in Japan (& elsewhere in SE Asia) that does house calls...

Is the inside of the tip round or something else? If it's hexagonal, that could be a bit-holder.

[Sazabi]

It's a round tube, albeit curved, as what can be seen in the picture.

Seems like a very big handle to house those two little blades 
Is the end of the tube sharpened (or does it look like it used to be)?

[Sazabi]

The end of the tube is rounded off; it somewhat reminds me of a strange take on a pipe tool; the tube could be an awkward method of filling a pipe, while then using the same tube to tamper the tobacco; the nail file comes to a thin enough point to be somewhat of an effective pick.  This is all just conjecture, though.
