So just made my first knives, it was supposed to be a batch of 4 small kitchen knifes. 2 didn’t make it (see below) I made them out of 80CrV2 (or 1.2235 as we call it in Europe). Thickness at the spine is just under 3mm or around 3/64". Hardened at 830°C / 1526°F in my electric oven and quenched in canola oil (45°C / 113° F) 2 blades came out all bent (I learnt since that I am not supposed to stir them around in the oil) and I broke them trying to straighten them out before the tempering, gotta learn the hard way. But at least this way I could put them under the kids cheapo USB microscope. So here are the pics: The 1st one is of a knife that I had to put through the oven 3 times before the file would slide over it, the final time I left it 10 minutes in the oven. So in all it will have spend approx 20 minutes at 830°C. The 2nd and 3rd are from the second knife, it spent 6 minutes in the oven. What do the experts think about the grain?
