Mine was broken about 2 and a half months ago, was back to proper sparring session this weekend, and its broken again after one solid punch connected with it.
is this likely to be permanently weak?
.....yep I will also working on my guard & moving my feet more




)over the years and two reconstructions, it's still a bit bent but not as bad as it was. The last three breaks happened because I didn't rest it and allow it to set. I was told 6 months no contact before I go back to heavy sparring. I gave it 6 weeks and ended up regretting it, so give it a good long period so settle other wise it'll hound you and it'll play on your mind. A full face head guard might help also.
