This gyuto has been made to impress in all aspects!

The blade is made from cryo treated 52100 (high carbon ball bearing steel) hardened to Rc62-63, it's tough yet easy to sharpen.

The blade's surface has been treated to a triple layer mustard patina for aesthetics as well as for a reduction in (negative) oxidation and reactivity. This steel isn't so reactive that it needs this to be done, I simply wanted to try something different and went for it. The result is a unique one of a kind look that has some worthwhile function to it. This is the 1st Martell knife that I've made for sale with a forced patina and it's also the 1st knife that my daughters both tried to get me to keep. They love the pattern on the blade, they call it "marble".

The wa octagonal handle is made from figured AZ Ironwood paired with blond marbled buffalo horn on both ends. The butt cap is rounded.

The handle has been sealed with 9 coats of a varnish/oil finish.

*Please see close up pictures for details.

Blade pattern is beautiful. I mean the whole knife is but that in particular is really cool. How's it done?

The mustard patina is a pretty simple thing to do yet everyone has a slightly different way of doing it though and there's about a gazillion patterns that could be made, imagination is the only limit here.

I did this one by polishing the blade up to the normal point where it's all finished, ready to go. Then I applied splotches of mustard, being sure not to cover the blade completely. Let it sit for an hour or so then wash off. I light sanded at this point. Then I re-did the mustard again hitting the spots that got missed on round 1. It sits for an hour, then wash, then repeat sanding and mustard again. After the last layer/treatment I washed and then buffed the blade lightly to make it smooth.

Beautiful horn, flows perfectly with the ironwood. Rounded butt-cap is a nice touch too!

Dave - nice work - really nice!
Still thinking about the Nakiri and classes, but had a financial set back and will probably have to separate them out.
I'll PM you Merry Christmas and Happy new year!

If this knife looks good in the photos I mean when you have it in front of you it’s another thing. Amazing.
