    I've been lurking some and have watched your progress threads. I really like the work you're doing and am curious what you'd estimate the hardness of the steel in your knives to be. Also, what do you recommend for sharpening?

    Thanks in advance for any info.

    Hi Byte,

    When I send them to Paul Bos for heat treat they get the "Cadillac Treatment" with 2 cycles of HT, cyrogenic quench and temper. He draws them down to what I ask for, which is 58-60 Rockwell Hardness.

    When I HT them I put them in the oven for 1 hour at 400 degrees, and I'd estimate the hardness at 60.

    Easist and best way to sharpen? If you're not proficient with stones then a $1800 grinder, which I use, or a Spyderco Sharpmaker. [beer]
