H2 Steel – H1 the sequel
Background
A recent Spyderco Byte has announced a replacement for H1 steel – H2. H1 is known for being a very high corrosion resistance steel used primarily in Spyderco’s Salt line of knives. I have a previous article about the design of H1 and how it “works” which you can read here. I am somewhat tempted to re-write large chunks of that article here because H1 is one of the most misunderstood knife steels but I am going to try to hit a few of the highlights without much explanation and I hope you will read the earlier article to understand what I am referring to:
Wood Knife that is 3x Sharper than Steel? Spoiler: No
Several people have sent me links to a recent publication about a process that increased the hardness/strength of basswood. They then demonstrated the success of their processing by making a knife and a nail out of the wood. See here for an example of one of these articles: https://www.cnet.com/news/scientists-create-a-wooden-knife-thats-three-times-sharper-than-steel/
