Graph Tech PS 8560 00 String Saver

The Graph Tech string savers replaces the standard steel saddles on a TonePros bridge. The strings glide easier over them, and therefore reduces string breakage. I also found bending to be easier. They're easy to swap and require no filing. If you however want them to fit better on heavy gauge strings, you could file down the slot with the actual string. They also last longer than the standard steel saddles, and are corrosion proof.

I got these to replace the worn saddles on my tonepros bridge for a Warmoth project. Since these have been on my guitar sounds a little louder acoustically and perhaps a little more midrange, but I'm not sure; it just sounds a little better to my ears. Intonation is great and I've not broken a string since having it on.
