The Dalstrong Quality Control Problem
On paper, AUS-10V at 62 HRC should deliver good edge retention. In practice, Dalstrong's Chinese manufacturing introduces significant quality control variability. Third-party hardness testing of Dalstrong Shogun blades has returned results ranging from 58 HRC to 63 HRC on supposedly identical knives.
Shun's manufacturing in Seki, Japan produces much more consistent results. VG-Max at 60–61 HRC is reliably achieved, backed by a lifetime warranty with strong customer service history.
Edge Retention in Practice
In ideal conditions with a well-hardened Dalstrong blade, edge retention is comparable to Shun VG-Max. In real-world testing with multiple production samples, Shun's consistency means their edge retention performance is more predictable. The "average" Shun outperforms the "average" Dalstrong due to manufacturing consistency differences.
Shun VG-Max delivers more consistent edge retention performance than Dalstrong AUS-10V due to superior manufacturing quality control. For reliable, consistent Japanese kitchen knife performance, Shun is the safer investment at a modest price premium.
