I heard Onoto has it's own in-house nibster, that's unique. Does lifetime warranty apply to all the ONOTO pens?
I believe that person is Mr. Binder. I would think that every pen company should adjust its nibs prior to sale, especially considering that these are often items costing several hundred dollars. Having said that, I know that some pen companies have better quality control than others. Most reputable companies will repair or replace a defective nib, but what a hassle to send a pen back and forth. Consequently, I purchase almost all of my pens from established nib tuners. They usually provide this service for free with the purchase of a pen. I didn't find any explicit statement of a lifetime warranty on Onoto's website, but since they are a very small quality goods manufacturer, I would guess that they would stand behind their pens. The last thing they need is some disgruntled FPNer flaming them.
Recently, someone in the classifieds was selling his Yard-O-Led to purchase more Onotos. I like my Onoto, but not that much.
I do have two minor complaints about it, The clip is very tight; it is hard to clip it to my shirt pocket. Also the cap takes six turns--I counted--to close or open. That is quite a few. Some Nakayas do take that many, though. Everyone I have shown the pen to has admired it. It is a pleasure to write with. I keep it filled with dark Diamine inks, currently Denim. British pens get British inks in my house!
I guess that you are seriously considering an Onoto. I suggest buying from Richard Binder. He can get any of the models available in England, just look at Onoto's and his websites. I will buy another someday, although one is not currently on my shortlist. Although, the sterling silver Magna is a truly stunning pen!
Best of luck,
