I made a Majestic Jr. for a customer that has been using the same pen for over 5 years until her puppy used it as a chew-toy
Got a call from her this morning about the nib digging into the paper. She is left-handed and bought the old pen at a left-hand shop in the UK and never had this problem. Most of her writing is on 3 X 5 index cards which is not the best surface.
Do they make special left-hand nibs or can a regular nib be modified for a left-handed user?
Larry, Yes they do make special nibs for lefties and there are several folks around the country who specialize in custom grinds but but you may not have to go to that trouble, it cound be that you just sent her a bad nib.
Did you test the nibs before sending it out to insure it wrote smoothly?
I write left handed and test every nib I send out with a pen unless the customer request that I don't, which has not happened yet.
If you look at the tip of a nib you will see that it has equal sized "globes" on either side of the slit so writing from just about any angle will be close to the same. Since most lefties tend to do more pushing than pulling when writing, slightly misaligned tines are more of an issue than one writing with their right hand.
I have experienced scratchy nibs, nibs with poorly aligned tines, etc so it pays to test and fix them before shipping.
Is there a chance that her custom nib might fit the feed on the pen you sent her? If not, test another nib to make sure it writes smooth and send it to her.
