if these TCT cutters are the same 'TCT' the blades use then they would be cactus with the 'odd nail etc'. The only benefit behind TCT slabbing chain would be the longer life in 'clean' timber and against 'nails etc' it would be useless.
Normal chain doesn't mind the odd nail, you just give 'em a touch up and off you go again, with TCT chain the cutters would just shatter... no more chain:(
