Introduction: Making a Removable Sternum Strap

So you've got a backpack with a "permanent" sternum strap?
In this instructable I'll show you how to make it removable

Step 1: What Will You Need

For this instructable you will need the following:
  • A backpack (of course)
  • A dremel or file
  • Some sand paper

Step 2: Cutting

Use a thin cutting disk and cut carefully until you almost reach the strap.
Repeat for the other side.

Note
You can use an image of a Split Sternum Bar for reference

Step 3: Remove and Widen Gap

Now gently remove the sternum bar (it's still a bit hard to do that, but soon it'll be easier).
After both bars are out, use a thicker cutting disk to widen the gap.
I used a different kind of split bar for reference as seen in the pictures.

Step 4: Sanding

Sand the imperfections and round the sharp edges a bit.

Step 5: Final Result

That's it! You're ready to go!


You can use this new feature to convert from using your backpack for hiking to going to school, office, etc.

Fantastic idea! I've seen this design on sternum straps and I've never thought to modify the ones I own even though they bother me on occasion. Thanks for creating this instructable.

Overall, does the slide feel less stiff? Can it be twisted easily?

It seems there's no effect on all on stiffness, comparing to it before it was cut. I think the bar's slider piece (one in the middle) is taking most of the load, and since it wasn't cut, there is no change.

i wouldve cut an or filed the short stubs away tho

That won't be a good idea, since the shorter stubs are stiffer and provide more stability in relation to their size.
