Centipede Titanium Ruler Small Metal Ruler - Portable Everyday Carry Pocket Rule Keychain Tool - Functional, Lightweight, and Durable Keychain Measuring Tool

This little ruler is pretty sturdy and fits nicely on a keychain. I am a tracker, so need to have a scale to include in photos that I take of tracks. This one is always handy, since it's sitting there with all my keys. Nice little ruler and photo scale!

I swear by this stylist tool. It is so sturdy and scratch resistant like new from day one after 2yrs. I use it all the time from pressing elevator buttons to pushing in the trash door at fast food restaurants. It is like an additional finger to avoid touching germy surfaces. You will find all sorts of ways to use this tool. Measuring is so convenient. I got one for boyfriend (germa'phobe) and he loves it even more than me :)

Don't expect perfection... The dimensions seem accurate, however my 3cm polished line is off.. It still works ... But I'm disappointed with this error.

Definitely not something I use on a daily basis but every now and again a 3 inch or so measurement has to be done and this 'pede has been on my keyring ready for action since day one. It's light and small enough that I forget that it's on the ring until I need it. I almost didn't get it, but I'm glad I did..you know, for those random times. Great EDC item.

I bought this for my keychain, but I find myself rarely using it. It's a neat tool to carry around though. It's titanium, so it's got more use that just a fancy little ruler. Really lightweight, and the clip is surprisingly sturdy.

I eyeballed this thing for months before deciding to pull the trigger. It's a neat idea but I didn't know how much practical use it would get, being only 3" in 1/8" increments. But I actually have been using it quite a bit, more than expected. Not just to measure objects, but as a visual aid to envision the size of something based on specified measurements. And aside from novelty purposes, it actually helped me in a work bind. It's not really my responsibility but I found myself helping out a co-worker while he was away on travel by going to the hardware store and picking up some washers. I had the screw it was supposed to fit around and a spec for the outer diameter. The washers were labeled with size numbers, not measurements. Had I just been eyeballing it, I would have picked up the wrong washers, one 1/8" too large OD. The Inchworm let me easily identify the correct washer on the first trip. I didn't buy it for that reason, did not expect to have to do that task, but it sure came in handy when the situation came up. I do think the optional clip it comes with is too big, adds too much length to how it hangs off your keychain. I attached it directly to my quick-release "spider" keychain (like the "patent" keyholder) using the provided split ring and it's perfect.

Came across this item by chance and I knew I needed it! It is prefect for carrying around on your keychain, as it is small and very lightweight. I will be using this a lot and I am sure it will have more uses then I can think of right now. Seems very well made and should last a long time since it is titanium.

Poor quality control. I ordered 2. One was good, the other was missing a key ring and the machine Mark's for measuring was off all over and the rod was longer which makes it useless for measuring anything.

Simple tool that is perfect for those little alignment jobs
