The Inchworm is a functional keychain accessory that you'll use more times than you ever thought. A "ruler in the round", the Inchworm is a rod of 3/16" diameter 6Al-4V grade titanium with grooves cut at 1/8" increments up to 3" long. The outside surface is bead blasted to a uniform matte finish, and new grooves are then cut at the 1/2" marks and 1" marks for ease of reading.
The Inchworm is made of extremely hard 6Al-4V titanium. Titanium is known for its corrosion resistance, and has a very high strength-to-weight ratio. It is typically described as having the strength of steel with a weight comparable to aluminum.
Why would you carry a ruler on your keychain? The real question is why not? Think of the possibilities!
- Check your tire tread depth
- Check the width of a broken fan belt or hose for replacement
- Checking screw lengths
- Comparing different product sizes at the store
- Visualizing the size of a product based on reading product size specifications
- Comparing the physical size of a part with the product packaging specifications at the store (i.e. buying a replacement plumbing fitting)
