Knifemaking: Kitchen Knife Made With Scrap High Carbon Steel

0 Просмотры
Making a fine cutting tool out of cheap materials and scrap pieces, using many of my homemade tools and jigs and various vintage equipment I restored in videos during my years on YouTube!
I forgot to measure the end product on camera so here are the specs:
The blade ended up 145mm long and 45mm at the widest. Overall lentght 255mm, thickness tapered from to zero. Steel is 1070 (aka C70) high carbon steel, differentially heat treated with edge hardness between 50 and 55 Rockwell.
Handle is made of tabilized okumè and olive burl wood, with red (and a line of grey) felt liners, fixed to the tang just by friction in a japanese traditional way with split dowel.

Here are some of the videos where I go in more details about some of the tecniques used in this video:
