Powder Steel (R2, SG2, ZDP189, HAP40) - By Price: Highest to Lowest

If VG10 is the knife makers steel of the moment then Powder Steel is the knife makers steel of the future. Also called High Speed Steel, Tool Steel or Die Steel this is great stuff. It’s generally found in hard wearing tools like dentist drills and tools used to cut metal. Very hard and capable of keeping an extreme edge for an extended period of time. Knives made from Powder Steel perform like few others. These are serious precision instruments and must be treated as such. I would even say they need to be babied a bit. With these knives one must accept that the blade will chip from time to time, but it’s a small price to pay for the insane performance.
