80CrV2 vs 1084
80CrV2 and 1084 are both simple, forgiving steels popular with bladesmiths, and they perform almost identically in day-to-day use. The real difference is a small vanadium addition in 80CrV2, which refines its grain and adds a bit of insurance against grain growth if a blade gets slightly overheated during forging.
Quick Verdict
These two are nearly interchangeable in practice. 80CrV2's vanadium addition gives it a small edge in grain refinement and forgiveness of forging mistakes, while 1084 remains the more universally recommended default for absolute beginners due to its slightly simpler, more predictable hardening behavior.
Toughness
Tied. Both are among the toughest simple steels available, well suited to hard-use forged blades and choppers.
Edge Retention
Tied. Both offer modest, comparable wear resistance typical of simple carbon and low-alloy tool steels.
Corrosion Resistance
Tied. Neither has meaningful corrosion resistance and both need the same regular oiling and drying.
Heat Treat
Very similar. 80CrV2's vanadium addition gives it slightly better grain refinement, offering a bit more forgiveness if a blade is briefly overheated during forging, while 1084 remains simple and predictable to harden in ordinary oil.
Grinding
Tied. Both are among the easiest steels available to grind and forge.
Best-Use Scenarios
Choose 80CrV2 for forged blades and choppers where a small margin of extra forgiveness against forging mistakes is welcome.
Choose 1084 as the most widely recommended default first steel for stock-removal or forged knives alike.
