San-mai

A 230mm Wrought Iron San-Mai Sujihiki

(Written June 2023) Here I have a first for me, a wrought iron san-mai sujihiki with a birdseye maple handle. I had originally set out to make a 270mm, but owing to a very thin core and .008″ of offset in my drawing dies I ended up with a 2mm wide place in the edge where the cladding crossed the core, so I had to shorten it. Nevertheless I would say my first foray into forging wrought iron san mai went well, and I look forward to using more of this material in the future. This wrought exhibits a lot of character, even a somewhat frosty look up close, and as I discovered during the etch, patinas with some variation in colour. I’ll be very interested to see how it looks after slicing up a hot roast or two.
