These are three small african knives. Although they are small, they are fascinating :
1. A finger hook from the Karamajong in Tansania. What's special about this one is the fact it has a double hook. Most of them only have one hook. Can be a gruesome concealed weapon.
2. A small knife with ivory handle from the Lega or Leka tribe. (length : 23 cm)
3. This is also from Africa. Don't know the exact origin. Lenght is 11 cm with a wooden handle (3,5 cm). The upper edge of the blade is sharpened. Perhaps someone else knows more ?
