There are really two issues here. One is the choice of names. I agree that they are pretty bad. The automotive guys have the same issue. In my opinion, that's all a product of substandard marketing courses in MBA schools. Having spent 36 years in marketing, one thing that I know is that names don't sell the product. Product quality is what sell.
The issue that I'm more concerned about is the choice of designs. I understand that PSI sells kits to pen turners, and presumably they have the data to confirm that pen turners want to buy what they are selling. And presumably, the pen turners they sell to are convinced that those designs are what their customers want to buy. And if that is the case, then there is an awful lot of bad taste out there.
But the designs that are being offered simply don't appeal to my taste. I don't care for guns, and refuse to have anything to do with pens that look like guns or ammunition. The 'steampunk' stuff is simply ugly. They have a lot of designs that are overboard with 'bling' - to the point of being tacky.
I much prefer elegant simplicity - plain, sleek designs where the metal components don't fight with the turned wood for attention.
