I have handled one BilletSPIN pen before and was impressed with it.  It was a heavy copy though – stainless and brass.  I love those two metals, but for a daily driving pen, I tend toward something lighter.  This answers that request – it’s titanium!  Also the clip is updated…. otherwise very similar pens.  Read on for more pics and thoughts!

Official Specs and Features

Here’s the official product page.


There are many versions of this pen.  Mine is specifically with stainless steel (body) and brass (head and tail), but there are other metal options.  It looks like all the tubes are stainless, but there are tips and tails of copper, damascus, heat treated stainless, titanium, and timascus.  (Possibly even others).  These can more or less be mix and matched, with whatever pieces you purchase individually.  Prices vary by metal specialty.


This pen goes for $215 when available, and should be available on April 1, 2020 here.

Short Review

This pen is very well built, and the swappable parts are easy to swap.  The balance was a little off for me; the pen is a bit top-heavy.  Using the Parker ink refill is nice, because of the standard size.

Long Review

What’s Included

  • BilletSpin Titanium “Thunderstorm” Soul Pen
  • Slip-in carry case


The package isn’t really more than the “What’s Included.”

Build Quality and Disassembly

The build of this pen is absolutely exceptional.  I do appreciate that it sounds hyperbolic to say it, but it’s really true.  The craftsmanship on this pen is just exquisite.

The pen itself in hand feels excellent too.  The titanium tube has just a bit of [stonewash-like] texture, and the teardrops around the grip area mostly just signify where to grasp the pen; they don’t provide much extra grip.  That’s not all that unusual in this type pen.  The tip has a couple of rings, but that’s well below where I hold the pen, so they’re not providing grip, either.

The tip retracts fully of course, just to where it’s ready for clicking out to use.

The teardrop is a design seen quite a bit in custom machining like this.  The first instance I can think of (but surely not the actual first instance) is the Hanko ex11.2.

The travel on the plunger is almost a full centimeter.  The click is quiet, but audible.

As stated, the Soul Pen disassembles completely, and also easily.  These are pieces that might get upgraded …. replacing them is just a matter of unscrewing them and swapping them out.  The threads are long, and there’s absolutely zero chance these will come off on their own.  The o-ring helps with that.  Below is the tail end, including the pocket clip and clicky.


The tip also has an o-ring, also unscrews readily, and is also replaceable by many other metals and finishes.

Both ends of the body are threaded as below:

Here’s the mechanism, which connects to the top of the refill.  BilletSPIN makes almost all of those parts.  Just the o-rings and one other tiny part that they don’t make in house!

I’m no machinist, so I don’t know how hard these individual steps are.  I do consider it a good measure that BilletSPIN is able to sell all these other parts individually and know they’re going to be perfect fits.  That’s a sign of quality work.  Below is the brass tip from my other BilletSPIN pen, fitting perfectly on this titanium.

In fact all the parts are fully interchangeable.  The fit is exceptional, too – no issues at all.

As you’ve seen on the product page, individual plungers can also be purchased.  Once the pocked clip/tail is removed, the plunger may be removed and swapped easily.  Here is that page.




A big update to this (and part of the name in fact) is the updated clip.

The clip holds on a pocket quite well, and allows deep (enough) carry.  Since the pen is long and pretty heavy, the weight keeps it on a pocket very well.  The pocket clip is not removable (except in the sense that it’s completely unscrewable).

The new clip is very nice, and I’d consider it an improvement over the previous/first version.  I won’t say it works better, but it seems to match the aesthetic better.

For reference, here’s the original version side by side:

Also included is this pouch, which looks more like a sleeping bag for the pen.  Very comfy.


Included with the purchase is a Parker 0.7mm Gel ink.  A refill accessory kit is available for $7, which includes this ink, a spring, and the two o-rings mentioned above.

The ink is replaceable easily of course, and there are quite a few ink options in this Parker format.  To wit, you can get this to be almost whatever you want it to be.

Still, you’d like some writing samples?  Write?!?!

Handwriting’s straight up not my strong suit.  Bible verses might not be yours.  But BUT… I’m writing some verses daily (or attempting to do daily) that aim to help deal with anxiety.  That’s what these are.  These are the times we’re in!!!


What I like

  • Impeccable construction
  • Parker refill gives plenty of options
  • All the accessory parts, for tricking out the pen in tons of ways
  • Teardrop design fits right in with many the custom flashlights

What I don’t like

  • Heavy, particularly top heavy
