I don't know why, but more cracks and the cracks that already formed are getting deeper. For example, a new crack just showed up where the tang is and it's growing. Any help is appreciated. I don't know the issue with the wood, but it seems like it's expanding and cracking due to some sort of stress. Even if it is fixed, I still question the integrity of the wood.That can be fixed and it wont crack anymore. If you want to pm me I might be able to help.
