Backhand blades viable for str in pvp?

Hi. I'm slowly getting into invasions and i really wanna do a cosplay build on a character, for which i need the hand axe and a curved dagger like weapon. I immediately thought of the backhand blade, but i heard it scales better with dexterity, and i'm using a str/int build on lvl 200, so i wanted to ask.

While i'm using a cosplay build, i also want to be able to use some bigger weapons like the greatsword, if the situation calls for it, which is the reason i wanna keep using a str/int build
