Hieroglyphs

Ka	The symbol is represented by two extended arms reaching upward or forward. While some scholars see the icon as a gesture of embrace others see it as one of praise, prayer or even self-defense. The concept behind the sign is just as elusive - the word ka is usually translated as soul or spirit but the ka meant much more. It may have symbolised male potency and in all periods it was used as a term for the creative and sustaining power of life.
Knife des	The ancient flint knife remained in ritual use throughout Egyptian history, even when metal knifes were available. The knife was a natural symbol of protection and retribution and also played a part in solar and lunar imagery. It also forms part of the "follower sign" or shemset.
