An unusual stiletto depicted in Indo-Persian miniatures.

I believe that the Sultan Suleyman's Mec got "new" fittings, i.e. the scabbard and passing decoration on top of the handle. The sword itself is earlier and very similar to the sword sought. The Sultan Ahmet's sword is also identical, alas no scabbard shown.
It is interesting that the general form survived in the later daggers of Central Asian steppe, like in the Teke Kard below.
