The 450 Grit Diamond Matrix Stone is where bevel refinement happens in a diamond-focused Edge Pro setup - the natural next step after the 250 grit for cooks who want to work through a progression using diamond abrasive throughout rather than mixing diamond coarse stones with aluminum oxide finishing stones. At 450 grit the cutting action is meaningfully finer than the 250 while still removing metal efficiently enough to clean up the scratch pattern from the previous stone in a reasonable number of passes. The diamond abrasive handles virtually any steel without slowing down, which makes this particularly useful for high-hardness powdered metal variants that can slow aluminum oxide stones at this grit level.
The construction matches the rest of the Diamond Matrix lineup: monocrystalline diamond abrasive with tight particle size and even distribution, bonded to a precision CNC-machined aluminum blank that reduces bow and twist and ensures true, straight geometry across the sharpening surface. That flat, true geometry is the underlying advantage of the Diamond Matrix stones over conventional mounted stones - consistent angle delivery across the full stroke, no high or low spots developing with use, and no need to flatten. The scratch pattern at 450 grit is described by Edge Pro as superior, which reflects the monocrystalline diamond producing a more uniform surface than aluminum oxide at comparable grits.
Care Instructions: Rinse after use and store dry. Diamond stones do not dish and do not require flattening. Rinse swarf from the surface during use to maintain cutting efficiency. Keep dry between sessions.
