I believe that the Yelo Jakets are 440A stainless - good but not to the level of D2.
Mongo, you may want to look at Moore Maker - they recently added a few patterns that (IMHO) are made by Camillus - yellow delrin handles, and 1095 carbon blades, reasonable prices.
Moore Makers premium line is made by Queen, with 1095 and bone handles.
