At Knifeworks, you're buying from an authorized Helle dealer: every knife in this lineup carries Helle's patented three-layer steel, developed in partnership with a Norwegian steel mill since 1967 and still exclusive to their Holmedal factory. Available in stainless H3LS and carbon H3LC, this construction sandwiches a razor-sharp, hard high-carbon core between two soft, flexible stainless outer layers, so the blade holds a razor edge indefinitely while remaining virtually immune to snapping under heavy lateral leverage. Call 888-225-9775 — we carry these knives daily.
