Rashi Script or Reggio Calabria?
Rashi script was created in order to differentiate between Biblical verses and the commentaries
The Rashi script was actually not invented by Rabbi Shlomo Yitzchaki (1040-1105\4800-4865) and did not serve him during the writing of his commentary on the Torah; rather, it was the publisher who printed the first book in Hebrew who originally used the script.
Thus the Rashi script first appeared in 1475\5235, when the first Hebrew book was printed in the city of Reggio Calabria, Italy.
The book contained Rashi's commentary on the Torah, and the publisher designed a special script in which to print the book, consequently known as the Rashi script. It is based on the Hebrew-Spanish writing and was intended to assist people to differentiate between the biblical verses and the Aramic translation of the Scriptures.
Although Rashi never used the Rashi script, his commentaries were not written in the Modern Hebrew writing of today, but in a slightly different version.
As of today, most Holy Scriptures are printed in the regular 'square' lettered Hebrew writing, while the commentaries on the sides are printed in Rashi script.
The Rashi script has also been used by various Sephardic Rabbis, such as Rabbi Yosef Kapach and the Mekubal Rabbi Kadouri.
The famous kvittel of Rabbi Yisrael Dov Odesser of Breslov was also partially written in this fashion.
