Hello Oariff,
It's an early 20th century "tourist-knife" of good quality, see for example these three threads where similar carvings and fittings were used by different knives IMHO.

It's always used deer horn with a similar way of carving in a good execution. And with a good blade. Collectable in it's own way! Maybe all from the same workshop.
