The Aesop bowls have been mentioned in bowl threads quite a lot, and they are of course Sori Yanagi stainless bowls that can be had for about half what Aesop asks for them. There are actually several sizes as they are a part of a kitchen set I believe, but IIRC only the two smaller sizes have the straight sides; the others have curved sides like regular bowls. the straight sides are what I believe makes a bowl a little better at lathering, the brush hits those steep sides and flexes more than a curved side - but that is speculation on my part. I’ve noted that the beautiful Woodhead bowl, the suribachi bowl, and the melamin bowls pictured earlier also have these steeper, straighter sides.
If anyone likes the Aesop but wants a larger size, say like the 16cm Symmetrical Pottery bowls, Sori Yanagi make one. Image below, 13 and 16 cm.
Cheers, Steve
