had my endura ffg for well over a year now and have used it extensively edc. I think it slices better than saber grind delica zdp i had or the pacific salt i own which is pretty much the same blade size as the endura but is saber ground h1 steel. the ffg delica i have is also a slicing machine, i give the endura more use because of the blade length is more to my liking. There is a difference i think you can really see when compared side by side, not a giant difference, ymmv. I dont see why one would want a d4 or e4 in saber grind vs the ffg versions if it is going to be used. If you just want to sit and flick it open and closed and admire the grind then get the saber e4.
