The Kershaws use Alabama Damascus blades - real Damascus - from the folks who make it for Bear MGC. Both are from Jacksonville, AL - and an affordable entry into Damascus blades. Mcusta also sells Damascus bladed knives at a reasonable price, although their layered construction often culminates in a VG10 edge.
The top knife above is a Buck Custom Shop 110 with teardrop Damascus - a custom - and quite handsome - Damascus. The other two are Alabama Damascus blades - very good values for the cost, particularly if you want to try the 'micro-saw edge' of Damascus.
