Picked up an 180mm sankotu from Tsubaya. Is too small. However, I use it much more often than the Wusthof 9" chef’s knife. Mild lack in power vs. the Wusthof, but more precision for everyday items.
I think 210mm is the sweet spot for me, going from 9.5” (basically 240mm) to 180 is a huge jump. I use the 210 and a small petty for basically every kitchen task save for slicing bread and chopping up bones
Must have been 9" or 210mm!
I love my ZDP189! It’s a total b**ch to sharpen, but it retains the edge nicely so it’s not something you do too often.
