    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...

    AEB=L bad Heat Treatment?

    Well sorry to say, but this is not a very good way to save time and improve your productivity... you need to dial in every oven, and retest frequently and learn the oven specific vagaries of measurement and heating... doing it well is a substantial rabbithole... if you want that rabbithole...

    Post here for design critique.

    I run the 12" wheel slightly diagonal - but that recurve might be a problem - from the ricasso, the tip then ends under the centre line of the wheel, then you start drawing the handle away from flat with the wheel... The upwards slant of the edge after the belly then sorts it out that the tip is...

    I have a moral/ethical question on forging.

    https://www5.kau.se/sites/default/files/Dokument/subpage/2010/02/39_533_547_pdf_17397.pdf The CrC type carbide des seem to be just about dissolved at 1200C in this article, but n690 is not in it... i believe n690 has mostly CrC carbides... this piece suggests 1100C is enough... but 1080 clearly...

    Toothache

    Good luck with the pain. A whole clove bud on the tooth is quite strong anti pain, does nothing for the tooth though you still need to go get it pulled... my dad felt so much better he didnt go, and it became a large abcess

    Toothache

    That is indeed possible, but modern diet is to blame on a large scale a dentist called Weaton A Price did research to find the best diets for the british governnet, he tracked the degradation in teeth and fasciimaxillary structure in societies and basically found that within a single generation...

    I have a moral/ethical question on forging.

    Whaddaya mean my Stainless NieuWootz is nasty??!! ;-) :D OK, so essentially I quench from 1080- 1100C - (1080C usually stipulated as the max aus temp) would tempering high to set up small tempering carbides be useful? and then use 1040 - 1050C and quench and LN and temper? I suppose don't quench...
