I have a small silver knife that is of an odd design and I cannot think what it was used for.
Can anyone help identifying this for me? Also, any ID of the hallmarks would be of help as well.

Re. my little silver knife, this measures 16.5cm long.

Here is the reverse of the handle showing a second monogram.
