I have ww2 knives with worse condition leather work and blades, and old knives in very good condition as no doubt we all have. So looks can deceive, it all depends on how well things have been kept in the past. This looks like a sword from the western Sahara with a straight blade.
Looking at the fullers it could well be forged locally. Spear point blades are not unkown on the more serious fighting arm knives and other weapons.
