Thoughts on carbide trimmer

I have wore out the cutters on my RCBS like 4 times in the last 13 years. Anyone try RCBS carbide deals?

Carbide is about 3 times as stiff as steel, and one of the harder metals. I believe it is as hard as (or almost) sapphire, and you need diamond or something similar to cut it.

Anyways, they should last forever when cutting brass.
