Twisting a blade or wiggling it obviously has the potential to damage the blade, without seeing what you actually did, it wouldn't be fair to say one way or another definitively if there's a fault here or defective blade. There's been some discussion regarding edges overheating on blades due to carelessness in production. I would hate to be running a business and find out I had someone purposely lacking in performance over some personal problems. Hopefully everyone working over there takes pride in their work otherwise people will continue to make reviews when their knives fall apart. I had my own personal experience with a Bravo one having the Corby bolts come out after some batoning. So that was disappointing, I thought I used the knife what it was intended for but it fell apart. I'm glad I wasn't out camping in the middle of nowhere when it failed. I didn't bother sending it back after going online and finding some unfortunate stories of former customers being completely mistreated after coming forward, which was a tremendous turn off. If a customer is using a tool for it's intended purpose ( not torture testing with cinder blocks) and they suffer a failure, they shouldn't be ridiculed for sharing their issue. If a owner has QC issues, they should tackle the issue immediately and fire whoever is the culprit, regardless if that person is family or friend... If they're hurting your business, it's a no brainer. But people will run their businesses how they please, customers be damned at times.
