Product Description

The Pocket Engineer is the every-day-carry wallet ruler for engineering students and professionals.

pocket engineer corto bolsillo cartera edc mm acero mecánico civil maquinista mecánico carpintería

Laser-cut stainless steel allows a small, compact 3 inch form factor that easily lives in your wallet for when you need it.

We designed every single aspect of The Pocket Engineer to make it as functional and long-lasting as possible. You'll have a full drafting and measuring tool at your fingertips without digging out your 12 inch ruler. The laser-engraved unit conversions and engineering equations will save you time and keep you working on your craft instead of searching the internet or old textbooks for the exact numbers.

It's the perfect gift for an engineering student going off to college, an engineer's graduation, a passionate machine shop teacher or a professional engineer who loves sketching out new ideas at a moment's notice.

Engineering reference info

Packed with every-day essential reference info. Save time on homework with common temperature, pressure, power, mass and length unit conversions laser-engraved on the back. No more Googling or searching the textbook index.

Reflective forensic ruler

Laser-etched high-contrast metric scale shows brightly in an image to set the pixel:length ratio so you can measure any distance in post-processing if your Pocket Engineer is in the frame. Perfect for failure analysis or field samples.

Pipe ID measurement tool

The back corner has a handy little pipe or drill hole inner diameter measurement gauge from 1/8th to 1 1/4" openings. Just insert the corner vertically and read the markings it lines up with.

Perfect for any job site

Used by civil, mechanical, nuclear, and materials engineers on every job site imaginable. You'll always be ready for your next engineering challenge.

How do we make these?

The founder designs each Pocket tool with meticulous dimensioning, line widths, and spacing in AutoCAD after consulting experts in each field. Our factory partner laser-cuts the shape from 0.5 mm stainless steel and coats it in hardened black enamel. Then, they laser-etch the text and ruler lines. We personally inspect and package each one before sending to Amazon's warehouse.

You're supporting a small business in Columbus, Ohio, started in 2019 by a Ph.D. Materials Engineer who just wants to solve everyday problems in laboratory research. Every purchase gives us more time and resources to tackle these problems and make every day in the lab a little easier.

The TL;DR

  • Small business in Columbus, Ohio
  • Every product designed by a Ph.D. Engineer
  • Owner will personally respond to every message within 48 hours

3.0 out of 5 stars Bubbles/rust?
Reviewed in the United States 🇺🇸 on September 28, 2022
Generally, I think this is a well-made EDC object. It feels sturdy and should last a long time. Edges are crisp and the text is easy to read (just the right balance between being too small and illegibly busy). HOWEVER, the card that I received "new" has what appear to be signs of corrosion/damage (see blistering and brown discoloration in the image; you can feel them when you rub your finger against the card). Time will tell whether these spots continue to wear in my wallet (where it's going to be rubbing against other cards). I need the scale for documentation I'm doing this week, or I'd probably return.
