I can see great potential for this as a two handed weapon at close range hitting with the knob and stabbing with the spike. A small penetration wound in the shoulder say only 3-4cm deep would be made all the more awful as the weapon was withdrawn or pulls the target completely off balance. Let alone a full stab to any body cavity
I think it is a very good old piece very possibly 19th century. The silk thread sewing the leather is what is known as Wild Silk produced in West Africa, fairly course as silk goes and white to brown in colour.
