I would be curious to see how these stand up in terms of just wear and tear over prolonged daily use.
The BYRD literature says: "8Cr13MoV blade steel is similar to AUS-8 in it's properties and performance". FWIW.
Also, I should have mentioned in my first post that both the Meadowlark and the Robin have metal liners inside their FRN handles (the Finch and Starling do not, however)
