The metal version of TWSBI Diamond has been discussed internally for some times. We intend to create an internal piston filling mechanism so we can ware different meterial outside.

The first thought is to ware a metal body (like Iron Man? hahaha!)



Below is the first look of the proposal. Pls comment.

Looks sweet, although it's maybe a bit too angular for my tastes.

But I'd be happy with the 550 (or whatever the 540 with bits of metal is called) too.

Looks really nice. The only thing bothering me is the metal section. I find metal sections very uncomfortable. I prefer the one with the dark brown part in the middle.

I think if you offer a metal section it should be mat instead of smooth.

Perhaps offer the pen with both a plastic section and a metal one.

I have Cross Townsend, a Persona, a Diplomat, a P-75, and a Lamy CP-1. My perfectly balanced P-75 was by far the lightest full metal pen I'd ever held, up to when I got that CP-1 which is lighter than some of my plastic pens.

How heavy is your metal pen going to be.
Brass or aluminum?

Edited by Bo Bo Olson, 24 October 2011 - 08:27.

Semi-flex is an “almost” flex; not a ‘flex’ nib. It is great for regular writing. It can give you some fancy; but it is not made for real fancy writing. For that get a 'flexi' or a "flex" nib.

"

 

Wider than Normal does not exist. Wider than Japanese does. Every company has it's very own standard + slop/tolerance. Developed from the users of it's pens only; not the users of other companies pens. The size you grind a nib to, is your standard only. Paper and ink matter to nib width. Thank god for 1/2 sizes or it would be boring.

Why not use the same barrel design as the 530/540 but in metal? The smaller facets should feel more comfortable than the big facets of this prototype. They would also produce many slimmer reflections when rotated. IMO, diamonds with more cuts have more sparkle.

I prefer the knurling on the cap surrounding the TWSBI logo on the pen with the lighter band in the middle. Also, is that knurling or ink windows in the section on the same pen? I'm assuming it's knurling as it matches the lines in the blind cap. However, it would be nice to have ink windows somewhere on the pen. I also agree that shiny metal sections tend to get very slippery. I don't personally have an issue with that, but a matte finish or even mild ridges (emphasis on mild) cut into the section could overcome the slipperiness of the shiny metal.

All in all, a very nice pen design, one which I would purchase if it's as reasonably priced as your other offerings.

Edit: I see from the 3/4 view with the caps off that the section threads and maybe the band are actually clear? If that's the case, then the ink window issue is already taken care of.

I hope the weight of the pen is on par with the current 580, while the metal grip section is replaced by the other materials. It's very difficult to maintain good grip with the metal section.

Looks very interesting. I don't think metal sections have to be a problem (see the one on Lamy 2000, also a good example of how the barrel form continues to the section). The weight is always a concern in terms of balance but many of us prefer a heavier pen, especially a large one that doesn't require posting. For example, I prefer my Pelikan M800 to the old-style M600 I'd been using for years just for this reason.

New metal design looks too mechanical (mechanical engineer kind of thing).
A pen should look artisty yet professional e.g. 530/540.

The metal grip slippery issue has been noticed, not only here but also on other pen design, we will have to come out with a good solution.
The metal barrel can be by aluminum (brass may be too heavy), or other materials, like PMMA (by CNC turning) or even wood... we will consider weight balance and total pen weight.

I don't like the step down from the barrel to the section and I'd be less likely to buy it online if there's a step since I can't tell where it would be in my hand. A wider cap would let it post on the body and not the piston knob

I think it truly looks like an "Iron Man" ! The design of the pen is lovely and very unique. I would have the same considerations that have been voiced from other posters: weight, grip, etc plus I prefer a rounder shape but all in all it looks like it could be another winner for you!

Not bad but still not my taste.
I'm not comfortable with the design for the transition from barrel to cap, when capped.
Maybe another day...

Seems pretty nice, but as has been mentioned, I would prefer a bit more sophisticated design, something like 540.
Also, I don't like the "belt" which is between cap and barrel where the pen is slimmer than the rest.
And I would like to have different nibs to choose from, but it is not what are we talking about :)

I like the looks Speedy!

Points for thought, the shape of the metal gripping section looks good, shouldn't be slippery, perhaps as an alternative a durable plastic or even a rubber? I like rubber sections, but find their durability to be a problem.

I like the clear section for seeing ink level, very German looking, an alternative, perhaps a 'slot' or 'window' on the barrel of the pen?

Colors, these colors are great, but perhaps some other dark colors, blue and aluminum or gold and red? Variety is the spice of life! One of my favorite combos is glossy black with silver (rhodium) accents!

The step in the middle with the pen capped, it's ok, and not a deal breaker, but perhaps it could be hidden by the cap when closed?

I like postable pens, a cap posting system that doesn't scratch the pen, or make it very long, or top heavy. I have 2 of the 'inexpensive' Dantrios from Winedoc that are fabulous pens, and are intended to post but become very top heavy when you do. It limits their usefulness for me.

I know this is the design phase, and in all things are compromises. Your definitely on a good track, keep it up!

I don't have a problem with either the metal section or the step from the barrel, as I hold my pens lightly well down towards the nib. And I really like the proportions of the design, and would not like a cap so big as to post on the barrel rather than the filling knob. But it's possible to engrave or machine the gripping section so as to give it a texture that would be more secure for those who find the smooth metal a problem, and also looks good. I've just purchased a Nero Muse pen made by FPN member stubnib (Maurizio Stura), which is very nice in this regard (an engraved silver section), but other patterns are also possible. It may well depend on the cost and availability of appropriate tools.

The balance of a metal pen is more important than its weight. The center of gravity of the pen while writing needs to be between the web of the hand and the tips of the fingers -- it is crucial that it should NOT be behind the hand. This is why many larger pens are uncomfortable when posted. When prototyping, test with a range of users with different-sized hands to ensure comfort in use.

My personal preference is for the more complex top to the cap (behind/above or to the right in the various views), but for the smoky rather than the clear ink window. I like the basic design!

I like the big facets, the engraved section (it could perhaps be a bit more) the darker middle piece and the overall design. I love hefty, heavy, big pens so this would be right up my alley. Please ensure that the cap (when posted) doesn't rest on the screw in the back, that is my biggest problem with my Diamond. I agree, when it is a heavy pen, balance is important.

I have to say, I'd buy it, it looks lovely!

I also think it is too angular. I just don't think it would feel good in the hand. That being said, I have a bit of a bias. I like elegant looking things a bit more than industrial.

My first impression is : Rotring 600 meets Caran D'Ache Dunas. Not love at first sight, too straight forward angular without the subtle extra the 530 has in its body shape.
But I'll think about it a bit more...

I think too much is happening with the pen aesthetically (angular body; gold brass section; stepped section and stepped band) get it back to basics with the following:
Uniform colour for the piston and body (if you retain the hexagonal body)
Probably keep the section in the colour displayed (choice of gold or silver/rhodium) if you insist on a metal section perhaps a brushed finished to improve the grip ; and also a matching clip.
The body band could probably be a window band to display the ink capacity?

I like where your heading with this though.

Nervous? No, I'm just thinking...

For me it's a bit too many things, many different colours, many different volumes. I would prefer more continuity from the barrel to the cap in term of shape, and the same material and colour for the barrel and the blind cap, as well as for the whole cap. Consider a plastic section with an ink window also.

the step transition from cap to barrel,
when capped, the step seemed to be too big, but when not capped, just the grip and barrel, the transition from grip to barrel can become smoother, and it will be better for long time writing. So, this is a trade off we need to consider.
