Japanese steel that stays sharp 10x longer. Budget santokus dull faster than you can use them.
Why Not Just Buy the Cheap One?
Cheap santoku knives from grocery stores and budget brands use soft stainless that rolls its edge in weeks. Shun uses VG-MAX stainless steel and laser-thinned edge geometry. The blade glides through protein and vegetables with zero resistance—it's not just sharper, it's a different experience.
The Buy-Once Math
Budget santokus cost $15-30 but need replacing every 4-6 months or constant sharpening (which weakens cheap steel). Shun holds an edge for 2+ years of heavy use and professional sharpening costs $15 to refresh it. That's one $175 knife versus $200-300 in cheap replacements and frustration.
