Baking problems on one part of my mesh

I'm making a combat knife in blender 2.83 but my problem is when baking the blade part of the knife. Everything else is baking as it should with no artifacts. I think it's an issue with my Uv unwrap but cant be sure. The only thing that shows some result is when i'm setting the max rear distance values but even then it doesnt look right. the normal map is somewhat distorted. 

I will post screenshots and try to upload the mesh if anyone care to look at it.
