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

Handy but I usually forget I have it.

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.

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 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 :)

My only issue is that I wish the marks were a little thinner, or if the marks were small specific measurements themselves like 1/32 or 1/64 wide grooves. I had to get calipers out to make sure the measurements stopped in the middle or the ends of the grooves for better accuracy.

This thing is not a large object.

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.

So handy, makes it real easy to identify the diameter or size of a part. Can make the difference with getting the right one the first time. I've gotten many a strange look when I pull it out of a pocket, but exclamations of amazement when I explain it. Fits on my keychain and not as obtrusive as I thought it could have been.

Simple tool that is perfect for those little alignment jobs
