Mixed auction lot

[kisak]

At a recent auction the seme here caught my eye (well, that's what I think it is), and since the whole lot (all four items) went for nothing much at all, I thought it would be worth the gamble. 54cm long, somewhat hollow-ground.

I'm guessing the dagger (Khanjar or jambiya?) as well as the bottom two things (whatever they are) are all "made for tourist", but I'm mostly fumbling in the dark here.
