حجر تنعيم أبيض ناعم أمريكي 3/4 × 3/4 × 4 بوصات

Picked one up to clean the glazing off my water stones, and the 4-inch length makes it easy to control without slipping. The fine grit leaves a smooth, even surface without digging in too aggressively. Exactly what I needed for quick touch-ups between sharpenings.

Used it to true up a whetstone before sharpening my chisels—worked fine and did not shed grit like the cheap ones. The 4" length fits comfortably in hand and the square profile makes it easy to hit corners. For the price it's solid, though I can't say it's dramatically better than my older stone.

Was surprised how cleanly this stone dresses the edge without loading up – the fine grit leaves a smooth finish with just a few passes.
