I have turned a number of slimline pens, but my wife finds that they are not comfortable for her to use because her grip is very far down - close to the paper. She is holding the metal end (nib?) and has to grip really hard to keep from slipping down. The plastic pens she normally uses have a shorter nib, so part of her fingers are on the plastic/rubber of the body and the fingers do not slip.
Is there a pen kit with a shorter nib? The slimline seems to be about 3/4 inches long. Maybe something around 1/2 inch?
