The general consensus from what I've seen is that 8Cr is the way to go for a good, wallet friendly blade, I've bought an 8" Buck and a 10.25" Chinese knife, both full tang, the buck is 8Cr and the Chinese one is 5Cr, the buck cost me I think about 13 Australian dollars (yep, I'm an Aussie) and the Chinese knife cost me about 15 from memory, I was looking at buying another 10.25" that looked a bit nicer but it wasn't full tang and it was 420J2, so I have held back for now on buying that, and by the sounds of it I won't be getting it haha
