I have tested the YK, YKLE & I just got back from testing 3 RAT Cutlery knives(1095).
Edge holding, toughness & feel. Scrap Yard YK with it's Res C handle, HT & SR-77 is in another league over RAT cutlery knives. But saying that, I think for the money$(except SYKC) they are a good 'option', but, it's not the steel for me & my business. As they all lost there edge pretty fast, COMPARED to INFI, S30V(Strider) & SR-77.
All 3 here have superb edge holding capabilities, with the tests I have conducted. For the $$$ SR-77 is the standout! Just MO. Hope this helps <img src="/ubbthreads/images/graemlins/thumbup.gif" alt="" />
