i used to use those tct blades all the time in a jamb saw. much safer because you have a reference surface so less chance of the blade getting nipped... these can be used in an angle grinder if you know what you are doing, but not for cutting (severing material) never plunge the blade only use it to score the surface, its only really use for carving
plunge the blade into the material and then twist or lean your arms, its gonna kick like a mule!
i picked up one of the below chansaw blades in poland, never seen them in the uk,, again same principle dont plunge it, all spinning blade tools have the capacity for kickback of the machine or material,
its important to understand the cause of it so you can avoid it happening,
