Sometimes I see pen auctions with 14k nibs that appear as if the usual iridium tipping has been worn down to nothing. The cost of retipping is often more than the cost of the pen, so am unlikely to pursue the better option for cheaper pens. With an untipped steel nib, I can pretty much grind it to a stub and expect it to last a long while. With more delicate gold, however, I'm not sure how long an untipped nib will be good for. Does anyone have experience with this? Will an untipped gold nib likely last a good while?
