Actually the resharpening fee would probably be prohibitive, considering how many stones an belts he would go through:bigeek:

In my opinion Vickers is not the most applicable method for this, but the ivory tower people like it. They are calling out "tempered steel" to be approximately 55 HRc and this gold composite to be comparable to around 70 HRc.

I wonder, is gold fine grained?

It would be interesting to know how our favorite knife steels would work if used instead of gold in this same process.

It's the addition of boron carbide to the gold which makes the difference. So my question is: is this boron carbide only able to be dissolved in gold or can it be added to steel? I've always wondered what would happen if you added sub micron diamonds to steel.

my understanding is that they build a boron carbide substrate and inject the gold into that, filling the space between the boron. They don't actually mix the two together. They both remain two distinct components.

Heck I am wondering how I can get Devin, Del, Dave or some of the other great knife makers here to play with this and make me a 270mm laser gyuto...and the cost to make said knife.

So basically this material is just like cemented carbide, except worse?
