A knife made from SHKh15 steel. An interesting forging.
The video will again focus on ШХ15 steel; Evgeny sent us a blank for the experiments: / @evgeniy_varyagbranibor5333 https://vk.com/id21361592
The blank is interesting due to its structure, which immediately after forging was granular pearlite.
Knife maintenance modes:
Quenching 830°C + 5 minutes;
Tempering 180-190°C + 3 hours.
