PDT (PDTools) Premium Vitrified Diamond – Vitrified Bonded

Great product. I do recommend getting a condition stone, drawaing a grid on the stones and grinding it down flat. Mine is ever so slightly uneven….but there was some extra material, i disnt lose a millimeter.

A little conditioning withs conditioning stones and it was perfect.

I purchased the 225 grit stone for minor edge re-profiling and repair. Using diamond plates on minor repairs can cause a lot of deep scratches and chipping on high carbon steel knives. This stone does neither and performs well in this role. The.value proposition has yet to be determined. If this stone holds up over time, then it is a case of buy once, cry once. I suspect it will based on my limited usage. I use Norton stone oil when sharpening with it.
