ROTA

The Infinite Twist Pen

MAKING PROGRESS

UPDATED : 08/31/2025

We have a prototype... well two actually. Many more parts in the scrap bin as well. Still aesthetics to dial in and machining to refine but we are really happy with the direction. More updates to follow soon!

ROTA PROTOTYPING

UPDATED: 8/30/2025

The ROTA redesign is being guided by a few key principles.

  • Manufacturability
  • Implementation of texture variations
  • Functionality / Fidgetability
  • Assembly reliability

We are pushing hard toward this goal. Over labor day weekend Deylan and I are focusing on getting to our first full prototype on the pen. Diligently driving toward a product that will live up to the promise of the ROTA.

Executing on the Vision

We are currently working on a revision to the ROTA design with manufacturing in mind. This development process will take as long as it needs to.

ROTA UPDATE

Edited: 8/1/2025


First off, as always thank you all for your continued support in helping us make MachineWise the company that it is. We are continue to be incredibly surprised and grateful for the passion of the community around us. Running and growing a business like this is no small feat and it has been a continuous trial. We are as a company, first and foremost enthusiasts. We make the products we want to own and see in the market. We also make them to a standard that we can stand behind. A MachineWise product comes with a promise of machining excellence and pocket-ability. They come with our lifetime warranty behind them, a declaration that the product will last, but also that the company behind it will stand the test of time.

The story of the ROTA starts with the purchase of our Doosan Lynx lathe. We purchased our live tool lathe with a singular purpose: to bring the production of hardware for our core product lines under our roof. At the time we had a handle on hardware production and as a pen enthusiast I yearned to make a pen myself. With that in mind the ROTA was born. The ROTA was designed with function at the forefront. Seeking to make something fun to use and engage with that could earn its way into others EDC rotations. While the design executed on its intent for function and form. It fell short in a key area of being labor intensive to assemble. In that it takes a great amount of time to assemble an “acceptable” product. At first we thought this was associated with the open tolerances on the first production runs. However, as we refined the machining approaches it became clear that the issue was in the design itself. This realization comes off of having made a large production run of them and getting bound up in long assembly times. We have now arrived at the conclusion that the ROTA needs a redesign for production scale manufacturing.

I will never be willing to sell a subpar product or risk the sustainability of my company attempting to assemble a product at a loss of time. To be frank, MachineWise is small, and we are not at the point as a company where our existence is assured. Every day, month and year is an ongoing challenge to keep the business going and provide each of you with the products you love. The world is ever changing and our goal is to remain here for the long haul.

In conclusion the ROTA is not dead, it just needs time. Often I ask for patience and I will continue to do so. We will not take money for orders, preorders or the like until this product is 100%. Those that have been sold are examples of the product that took much love and finesse to bring to function. I greatly appreciate your continued enthusiasm around the product. When it is ready we will bring it to market in force.

We'd like to address some of the feedback we've heard regarding ROTA. Here's some of the common suggestions we've heard:

  • MachineWise should outsource the ROTA.

This runs contrary to the core ethos of the company. Manufacturing in-house is what makes MachineWise, MachineWise.

  • MachineWise should spin off the ROTA brand.

The pen design is currently not ready for mass production. It is something we may consider in the future after re-engineering. 

  • MachineWise should scale up to produce the ROTA.

If only it were so simple! The ROTA in its most recent production run has taken too long in assembly to be viable. At MachineWise, quality is always our number one priority and we won't compromise on any of our products.

  • Raise the price of the ROTA.

We don't plan to pass the price of a long assembly time on to our customers. Our goal is to make ROTA's as cost effective as possible to produce and manufacture.

Amazing EDC

Having a weakness for quality and unique pens, I was very intrigued when I was introduced to the ROTA pen. I got in line and waited for fulfillment and it was very much worth the wait. I have carried twist style, click style, and a variety of bolt action style pens and this is by far my favorite.

Although I am selfishly happy to hear the pause on production, (my OG ROTA is now a collectors item!), I am anxiously awaiting the V2 ROTA so I may add it to my collection.

Great work MachineWise and looking forward to the future.

Amazing Pen!

Tl;dr: Just buy it, it’s worth every cent!

Sorry for the wall ‘o text. It’s been very strange to have my love of balisongs, pocket knives and pens all converge on one company that’s producing a trifecta in all categories. The ROTA was truly a surprise, as I am extremely particular with writing instruments and knife companies tend to throw their hat in the ring with pens with varying degrees of success. Any hesitation I had in buying this was my own worry that MW would break their winning streak.

I have art degrees, draw and write A LOT and don’t give praise lightly on this topic. That said, the size, weight, and length are very important to me and the ROTA is as near to perfect as I’ve held. The diameter is exactly what I look for. I despise pens that are too thick or have annoying texture and you absolutely nailed it on this front. You also aced the length, It’s not too long or short (I’m looking at you Grimsmo Saga). I’ve heard people complaining about deploying it with one hand and I actually think you got this right. My issues with other machined pens are that they are either too easy to accidentally deploy, which leads to me not wanting to clip them to my pockets for obvious reasons; or the mechanism gets in the way when it’s deployed (bolts), which dig into the skin between my forefinger and thumb and annoys tf out of me. I think bolt action mechanisms are clunky, lazy design and are way overused. You managed to create a mechanism that is unique, fun and fidgety to deploy, doesn’t get in your way or change the form factor when deployed, and most importantly requires intent to deploy all while looking attractive. Well done! I’d nitpick about Parker refills but I’m fully aware that the refill dictates the size of a pen so I’m happy to experiment with finding a refill to my liking to keep this perfect form factor.

You just need to release them in fun anos and you’ll get me to buy another (or 2) like you did with the Sonora. My only complaint is what you are doing to my bank account, lol. Keep up the fantastic work!

A mechanism you must feel!

Infinite twist mechanism is fantastic. If you are into EDC pens or would like to own well machined pen. Look no further. Definitely one you must experience in hand.

The best fidgety pen out there.

Probably the most difficult pen to get as of now, just can't give enough love to Rota. The machining is simply top-notch. It's a real beauty. The logo on the cap is killer. Aesthetically, I find this checks all the boxes for what I look for in a pen. I have had my share of owning some of the best; this certainly trumps many. Absolutely no tip wiggle; the tip screw is deep, and the tolerances are amazing. Feels soft in a way that is unusual in a good way for a machined pen. With loads of love from India. Special thanks to Lance for letting me have one.

So fidgety

This pen is not only meticulously crafted, it has the fit/finish that has come to be expected from MachineWise. The infinite twist mechanism is also infinitely fidgety, and the pen has a wonderfully unique design. I love it❤️
