Kickstarter has an art project category, so pens could presumably easily qualify there...
I've seen quite a few pen projects on Kickstarter. Some rename the common pens instead of using the standard "cigar", "slimline", etc terms. Sounds fancier if you pick names that make sense...one of those used Australian woods and all of the pen styles were renamed after Australian cities. That's not intended as a complaint, simply explaining their tactic.
Some folks explain they're doing it to be able to afford a new piece of equipment and the pens, stoppers, etc are a reward along the way (vs. the entire thing just being a way to sell pens). The key is to price the rewards appropriately and to make sure supporters understand what they're getting as they're helping fund what you're getting...barely scraping by after Kickstarter and Amazon take their cut off the top isn't good business (but it is at least very good practice for pen making).
