Finally to the blade. Here is a view of the reverse ricasso showing the king & knight mark of WK&C, dating this piece to I believe pre-Imperial & the Imperial time.
The grip is fairly plain compared with other Fire Official models & made of a black wood. I'd love to say it's ebony but it doesn't seem as prone to drying/cracking as the ebony of SS dagger grips so I would think it's something else. This grip shows some dings & slight scuffs commensurate with modest period wear.
The blade shows a quite nasty sawbacl blade. But what else is that in the picture?
