It's a pretty odd knife. The handle would not be very comfortable to grip although someone went to a lot of trouble to make it. The blade on the other hand is a very poorly made blade, it has no nice grind lines and looks fairly thin and flimsy. Could just be a letter opener with a wide blade. Being as the blade is the main function of a knife and this blade looks poorly made and the handle looks uncomfortable to hold I do not believe it was made for hard work or heavy usage such as a trench or military use knife. It is entirely possible that it originates in the far east such as India, or Africa, both known for knives with poor quality blades and ornate handles. It does have that tourist grade knife look to me.
