Morie (守家), known as Morie because he resided at in Province, was a leading smith of the mid- period whose workshop stood adjacent to . Although no blade by Morie or his successors has been found signed "-jū," several bear the inscription "-jū," leading scholars to conclude that was a subdivision within village. The prevailing view posits two generations bearing the name: the first is regarded as a smith contemporary with Mitsutada, the founder of the lineage, and the second as a smith contemporaneous with Nagamitsu. However, a clear demarcation between the first and second generations remains a subject for future research, and there are also those who advocate a single-smith theory. The earliest dated extant work is a inscribed Bun'ei 9 (1272), and blades with the signature extend into the period as far as the Koan and Kentoku eras. In style, Morie's workmanship shows points of commonality with contemporary masters, yet retains a character distinctly his own.
The consistently identifies two distinguishing hallmarks of Morie's work: a that tends toward (standing grain) and conspicuous (蛙子丁子) within the tempered edge.

Notably, Morie's output encompasses a considerable range: from gorgeously flamboyant works in which large clusters become disordered into dramatic formations, to comparatively calm pieces tempered in quiet mixed with and , exuding what the describes as "a subdued, austere flavor." This breadth is itself regarded as a valuable document for understanding the relationship between Morie's workmanship and signature style.
Across repeated designations the affirms that Morie's finest works display forging that is "well refined" with "vividly standing ," a "rich in and " whose conveys "a full and gentle sense of ," and a state of preservation that is "extremely ." Works retaining an are singled out as preserving "the original state of an earlier age," and signed examples by the first generation are noted as comparatively few, further enhancing their documentary value. Extant by this smith are described as "a rarity today" of "high value as reference material." At his most characteristic, Morie produced blades that the judges "splendid in effect yet overflowing with dignity" — work that, while firmly rooted in the idiom of the -, achieves an unmistakable individual identity through the standing grain of the steel and the exuberant of the hardened edge.
