It gets its descriptive name from the traditional stone millstones due to its signature flattened top apex, wide dropped shoulders, and a broad, exceptionally flat \"W-shaped\" base. Grown to full wild maturity, this old-lineage variety is highly prized for its dense, shock-resistant wood-bone walls and its ability to develop a deep, high-gloss translucent crimson patina over long-term handling.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"12\"\u003e\u003cb data-path-to-node=\"12\" data-index-in-node=\"0\"\u003e[Product Characteristics of MP-1301C]\u003c\/b\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli data-path-to-node=\"13,0,0\"\u003e\n\u003cb data-path-to-node=\"13,0,0\" data-index-in-node=\"0\"\u003eThe Robust 45mm Low-Profile Form:\u003c\/b\u003e Measuring a substantial 45.0mm across the primary wide edge paired with a full 43.0mm belly depth.
