Why didn’t Itachi give Sasuke the Totsuka blade and the Tara mirror?!

This has always bothered me with how powerful these 2 weapons are it’s crazy that they essentially died with him like could he not give transfer them?! Like they would have been really useful against Madara and Obito

Also was I the only one who thought the Totsuka blade and Orochimaru’s snake blade were also part of the 7 ninja swords before we got all the swords in the war arc?!
