You can order one made for a lefty. I got mine from the Graph-Tech website. I filed down the center slot and a mm from each side. Works great and looks super on my Black Tele. Didn't do a thing with the string grooves.

Installed this thing on My strat and I love it. I have a Rosewood finger board so the dark color of it is cool. This was a very easy nut to install, all I had to do was file the edges down because it was too long for my neck, but the thickness and height was perfect. I now have great tuning stability and like the best action with .11 guage strings. I am going to order one of these for my Telecaster next.

While the product is as good as others have written, my problem with the nut overshadows those positive qualities. I have an older Squier Strat with a radiused nut slot and when I removed the center tab the nut goes too far into the slot causing the low E string to hit the end of the fretboard before the headstock. I even have staggered tuners that raise the E string a bit. I doubt if the slot was originally too deep because the original plastic nut wasn't very high and still didn't cause the string to hit the wood.

I ordered this baby and it don't go on a lefty. It's got a radius on one side that is backwards for a lefty strat. You might have to find a tech to put you a graph type of nut on it like I did.
