The 5160 carbon steel Ontario and others, including Buck's Ron Hood line, #060-070, are usually heat treated to a Rc of 54-56, softer than the Rc of 57-59 Buck treats their SS 420HC to meet. The 420HC doesn't have the bragging rights of some steels - but it is in use quite good - and not so hard to re-edge. The hollow grind means it is better at slicing - but I've chopped some small saplings down with a 192 & a 119. Oddly, I fish - and will clean fish with a pocket knife if I have to - but I haven't hunted in decades. I do have a collection of 'hunting knives' - which I use camping - or 'bushcrafting'. KaBar original combat knives are .165" thick of 1095 carbon steel - usually Rc of 55-56. I have their Becker BK2 and it's made of the same steel - just .25" thick - but, sadly, it's blade is only 5.5" long. I have the nicer looking ESEE RC-5 (Now ESEE-5), too - same basic knife as the BK2, just drags more in chops/deep cuts due to the pebbled finish - the BK2 is half the price too. These knives aren't so useful in making camp accessories - certainly not a whittler! The BK2 and ESEE-5/RC-5 are full width tangs and of a drop point design. The original KaBar fighting knife is a reduced tang (My Dad's old version broke at the pommel!), while the similar Bowie-style Buck 124 has a full tang. Choices...
