440C vs AUS-8: Budget Japanese Scissor Steel Compared
What's the difference between 440C and AUS-8 scissor steel?
440C and AUS-8 are close budget martensitic stainless steels with similar edge life (~700–1,000 cuts): 440C runs a touch harder (58–60 HRC vs 57–59) but its quality varies more by mill, while AUS-8 is prized for easy maintenance and consistent corrosion resistance — either makes a sensible starter or backup pair.
Both sit in the dependable budget tier, a clear step below VG-10 and ATS-314 on edge life. 440C is the long-standing baseline — solid when properly tempered, but under-hardened batches from weaker mills can feel mushy and dull fast, so the maker matters. AUS-8 is a balanced Japanese stainless loved for low-fuss upkeep and reliable glide; its edge life trails the premium grades, so stay on top of tension and servicing. For a first or backup pair, pick on price and feel — both will serve.

Which budget steel to look for
There’s no wrong answer between these two for a starter or station-backup pair. If you want the slightly harder edge and you trust the brand’s heat treatment, 440C is fine. If you’d rather have easy maintenance and consistent rust resistance, AUS-8 is the calmer choice. Sharpen on schedule either way — neither holds an edge like the premium Japanese grades, and that’s the trade for the lower price.
