Spyderco Nilakka : edge retention, durability, strength vs tough

[Cliff Stamp]

You're referring to Roman's book? But it's only in German, isn't it?

Yes, however there is a tremendous amount of it that is tables, numbers, micro-graphs, diagrams, etc. that are the same in any language. He has a wealth of data, the micro-loading alone is worth the book as it covers topics which cut through a massive amount of hype/misinformation and he speaks English so you can just talk to him about anything that requires clarification.
