This knife became an instant favorite in my selection; all Wusthof, Messermeister, and one Shun(an awesome gift, a Western Chef 6").
The Epicure Santoku is styled after the Wusthof Chai Dao profile. It has a fat blade with exceptional balance. I believe the widest point is 2 3/16". So, this does fit in the primary slot of a Wusthof knife block; 2.25".
This knife isn’t sold with an Epicure Set; the Chef knife and this Santoku would be vying for the primary slot, since the subsequent slots are smaller. I just happened to previously obtain a second Wusthof block, so I have a home for this knife. The issue with fitting into the block was a recurring complaint across reviews I’ve read.
My recommendation is to get this knife anyway and figure it out. My set-up is all my chef’s blades are above my prep station on a wall-affixed magnetic rail; a wooden style with hidden magnets. My two Wusthof blocks are freed up for my secondary and tertiary blades. Happily this wide Santoku/Chai Dao has a safe place to rest between uses.
The ergonomics are already a plus for the epicure line, but really shines with this Santoku, given the blade profile and weight. I have several Epicure, and I’m very happy I finally picked up this knife. It’s a great addition.
