There are two patches of relatively heavy rust on both sides of the blade—one larger, one smaller. However, as the blade wears down over time toward these areas, they fall well within the non-cutting ears (mimi) of the blade, so they will not affect its functionality.\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003cp data-path-to-node=\"1\"\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cem\u003e\u003cstrong\u003eAfter Mr. Ochiai Yuichi retired in 1973, most of the third-generation Chiyozuru planes are made by Ochiai Uichi's sons, Ochiai Giichi (落合義一，the eldest son) and Ochiai Kazuyoshi (落合和吉，the second son). After 1987, Yoshiichi's health deteriorated and Kazuyoshi was the only one who continued to work in the blacksmith shop. Therefore, most of the third-generation Chiyozuru plane currently on the market are made by Ochiai Kazuyoshi.\u003c\/strong\u003e\u003c\/em\u003e\u003c\/p\u003e\n\u003cp data-path-to-node=\"2\"\u003e\u003cem\u003e\u003cstrong\u003eI had this blade authenticated by Mr. Noboru Tsuchida, who confirmed that it is indeed the work of Ochiai Yuichi.
