The blade is hardened to make it strong and resistant to wear and tear. Hardening the blade involves heating it to a high temperature and then rapidly cooling it, which changes the molecular structure of the metal, making it harder. On the other hand, the tang is left soft to provide flexibility and absorb shock. If the tang were hardened, it would be more prone to breaking under stress, so keeping it soft allows it to better withstand the forces exerted on it during use. This combination of a hardened blade and a soft tang creates a balance of strength and flexibility in the overall construction of the knife. **
