Thank you all for providing your comments. I greatly appreciate your honesty and assistance!
Um, "ball point barbarian?" I guess I have to say,... I resemble that remark. But I don't have "jack hammer ball point hands". I have to draw the line somewhere.
Yes, I don't want to spend time learning how to use a fountain pen. That time will come, but not now. To be more specific, the primary purpose for me getting a fountain pen right now is for signing cover letters and thank you notes. I am not going to have space to do the whole "John Hancock" type signature. But I do want to differentiate myself in regards to my (business) signature on such correspondences. Given this additional information, could you please comment again on my initial stab of choosing a FP for such purposes? Am I missing any other specs?
Fountain Pen- Souveran Fountain Pen M 800 (good choice for a ballpoint barbarian?)
Nib Tip Shape - Round nib?
Nib Grade - M, B, or BB?
Nib Type - Firm (is this what people mean by "nail"?)
Hello NJGuy! Welcome! I'm not sure where all the ballpoint barbarian stuff came from...
For signatures, I think that the M800 or M805 (the "5" just means silver instead of gold trim) is a great choice. It is a substantial pen, a beautiful one.
I think that if I were planning to use the pen mostly for signatures, I would probably pick a B or BB nib. Maybe for flair, I would go for the BB.
I'm not sure anyone has mentioned this yet, but you should at least consider purchasing the pen from either nibs.com or Richardspens.com. Both sites are run by "nibmeisters," who will make 100% sure that the pen writes smoothly before sending it out to you. (Pelikans sometimes leave the factory in less than perfect writing shape.) In addition, you could give either site a call and tell them what you are looking for: they will be very helpful.
As you probably know, you'll also need to get some nice ink(s) for your pen. My favorites are Pilot Iroshizuku inks, and Diamine inks. Both brands have wonderful vibrant colors--and good writing properties. Take a look at gouletpens.com for an easy to navigate selection.
Finally, when you get your pen, have fun getting a feel for it!
Good luck! and I hope you'll let us know what you decide!
