Is MagnaMax REALLY Stainless K390/10V?! @SpydercoKnivesOfficial Proto-X Corrosion Testing

Please excuse the first few minutes of the video???? I thought it’d be cool to see if the hot steak or lemon would stain the blade. As you can tell, it’s the boy’s dinner and he is hanging around. He is currently going through a diagnosis seeming to lead to Autism. He struggles speaking at times&speaking appropriately. Please have grace with him???? Thank you!
