    Meat Fork Construction

    i usually just aim for the lowest hardness that wont cause it to get bent, and in my case keep the stainless knife steel stainless... lowest hardness, because i want the knife edge to stand up better in a knife to fork contact situation.

    Mechanical Engineer designed his chef knife.

    cleaver / chopper---> flatter belly, unless you just like the shape and will use it as a normal chef's knife, minus the tip for detail work... ask him to take a look at Bunka, it is kinda a blend between a nakiri and a gyuto, which ends up being very suitable for general purpose work and light...

    Heat treatment or geometry, which is more important?

    amen... i have to add, my experience is that high carbide volume steels need more hardness, before you can get a really nice edge... they are a bear to remove steel, regardless of their hardness...

    Heat treating 52100 and 80crv2

    Kevin, I am intrigued by that... I thought the +/- .8C one would use around 1490F-1500F? I also believe there are 2 grades that are often used interchangeably for 80crv2 - which may be where my confusion comes from

    ceramic belts?

    the requirement for more pressure and speed goes up as you go lower in grit i find... i literally can't apply enough pressure to make full ceramic 36 grit work well on hardened high wear steel... so i use 60 and 80 grit at a fairly low speed, with as much pressure as i can find. then i clean the...

    Testing a knife

    One thing alluded to above, but not expressly stated... if you dont have it in the oven for long enough, the steel is not austenitized fully, now for 1080, it is unlikely to be an issue - the moment the steel is up to temperature... but it is really possible, unless the thermocouple sits against...

    Scimitar help.

    Well I am necro threading today, the Scimitar is flat near the heel of the blade, that is for chopping / cleaving, so the thicker stock and the extra height is for strength and knuckle space, it is not a heavy cleaver, but must withstand a little torgue going through joints... and also a bit of...
