An Ultra Thin 250mm Gyuto-Matched Pair

Have you ever wondered what it would be like to own two otherwise identical knives made from different steels? Well here’s your chance!

This was a fun project, an ultra thin 250mm gyuto-matched pair in the ever popular KS style utilizing two of my favorite steels, AEB-L and 52100. Admittedly these knives came out a bit thinner than I intended, but that’s probably in keeping with their parent design. The weights, tapers and grinds are very nearly identical on these blades with similar degrees of convexity and nail flexing ease.

In all the pictures and measurements the AEB-L is getting first billing. Where values are identical only one will be given. You’ll also notice in the pictures that the colouration at the neck is bolder for the 52100, if you’re having trouble remembering which is which.
