My Gripper Broke Closing It, This Happen To Anyone Else?

I know a lot about metal. If you can take a high-res photo the break I can likely tell you what happened other then you being too strong.

My camera is really old I will try to borrow a better camera. I tried zooming in on the break but it comes out blurry so I doubt it will help.

What do you think may have caused it though? I have not cleaned my spring in a while but I don't use much chalk in general.

Kind of bummed that it broke but if there is something I could have done maintenance wise I will make sure to care better for the other grippers I have. I just didn't think this could happen.

There's no way to tell for sure without seeing it up close but it was very likely just a flaw in the wire that got worse over time.

When steel breaks it leaves lots of clues behind.

Here are a few clear examples of clues left behind.

These are really zoomed in but it makes for a clear example

Secretly I've always wanted one of my grippers to break, but alas, no dice. If it happens, I bet it's my #1.

Modern steels are amazing. Breaks like this will only become more rare at the years drag on.

I have only heard of this happening to #1's, and usually after a decade or so of reps. I agree with Jared - given where it broke it's like a small defect in the wire at that point - too many dislocations, a localized impurity, etc.

I wonder what ironmind would say

Maybe an autopsy is in order. . . .

That looks like a pretty clean break in comparison to the torsion springs that break in my pony clamps every 12 or so months (due to understandable fatigue).

I'd guess it's a badly located (and very rare) defect.

On the off chance that you trash it, I'd buy it to use the handles on my silvis adjustables. I know if it were me I'd keep it though.

Handles are epoxied on.

There are ways to deal with that.

Yes, a beautiful Silver Elite many years ago. It just snapped. Those silver elites were unique too at the time. :(:(

Loving all the metallurgical knowledge on show in this thread. Never though I would see dislocations (small faults in the metal lattice structure that can move under stress) mentioned on this site.

oh, and nice SEM image of the fracture face.
