    New Line - Integral full tang mono

    I have been working on this on and the forging and heat treatment of this particular shape in this particular steel on and off for about three years.
    It started with a Parer idea based on an old Sheffield pattern, but with a sweep to the heel rather than the huge chunk of metal at the heel of this design of sheffield knife you will be familiar with.

    Mean time I have been playing with the forging process and die shapes to get these as close to all forged as possible for larger knives. This is not a huge knife but is a good test piece to base future efforts.

    The steel is a very high carbon with tiny amounts of chromium and manganese, it is a shallow hardening steel and gets extremely hard, with the heat treatment I have developed it is edge stable at almost full hardness. This example is 65/66hrc!! And shows some nice edge flex, It would chip against hard steel or grit, but it would chip clean with no distortion. There is differential hardening using clay. I wanted to take this test piece to the limit, but I would fear substantial chance of tip loss at this hardness, commercial pieces will be a little lower at 64/65. Though I wanted to test its usability at its absolute limit. I can tell you it was an ass to hand rub!

    The Shape is entirely forged to begin with, blade shape, taper, and bevels, this all helps with a shallow hardening steel all helps in the heat treatment, though hard to achieve, (why Ive been so long working it out).

    So this is still a working process, Larger knives will have fuller handles from larger stock, the parer versions are very cute..... Unfortunately I broke the parer example on the hardness tester, which gave me a nice chance to see the lovely grain I have achieved with the steel,

    Handle on the test piece is Maple one side and spalted tamarind o the other, kind off offcuts two for one special.

    Anyway here are far to many pictures. This is my test piece on which to base future work with design tweaks... not for resale.































    Told you there was allot of pics.....was finding it rather photogenic

    Blade length on this one is 140mm 35mm tall.
    Thanks for looking and commenting your feedback.

    STUNNING........ Very streamlined look.
    Good food is essential, where knives are an integral part of the process.

    It's beautiful Will. The handle appears well suited to the size of the knife.

    Thanks all, Chef your right however I tend to avoid the term silver steel, it is a broad term which can be applied to a range of steels. But its an engineers grade steel around 1.2-1.3 carbon, with a little manganese and a little chromium. Usually unusable above around 63 hrc but with my heat treatment it is edge stable at 65/66hrc, though I wouldn't want to stab it in the sink with this ht, could loose up to about 2cm off the tip. Therefore will be using a little more clay and a tad softer for sale pieces. Edge characteristics its fine/medium courser than 01 but finer than 1.2442 feels and sharpens like a white steel thats taken to the limit. I will let you know how the edge behaves after I have abused it for a while cooking at home. Oh and Happy easter everyone

    I've never been a fan of western style handles, riveted handles or integral bolsters but that knife is absolutely beautiful. I think it's the best example of your work to date.

    That is absolutely mind blowing. I've never seen anything like that on a non commercial knife. I don't have a broad enough vocabulary to even began to describe just how beautiful that knife is. Keep up the good work.

    That is really cool. Good job!

    My very first though was: 'I want one'

    It is very novel. I am wondering what inspired it?
    Economy of means leads to dexterity of will.
