Looking for a quality fixed blade between 3-4 inch blade. Must be quality steel somewhere around 154cm hardness would be ideal. Knife will be batoned and used as a prybar sometimes.
Well, first of all, 154CM can be heat treated to different levels of hardness. Second, assuming we're talking the typical 59-61Rc hardness that 154CM is heat treated to for most applications, I think you're going the wrong direction. Unless you're willing to go to a much tougher carbon steel like 10xx series, O-1, or 5160; I'd go with a softer heat treat to reduce the chipping and breaking on a knife you intend to pry with. Third, regardless of steel and heat treat, I would look at blades that are designed for prying and hard use.
Here are some places to start:
For harder heat treat all in one:
Boker Plus Cop Tool
CRKT Graham Ringed Razel
CRKT Graham Stubby Pocket Razel
For Softer heat treat heavier prying use:
CRKT McGowan MAK-1 I like this option quite a bit because it's a lower carbon stainless with a softer heat treat for better use as a prying tool.
At those prices, I'd carry one of those tools on the belt for prying, heavy chopping, and other abusive tasks. I'd add a high quality folder clipped to the pocket for EDC cutting tasks.
Last, if you want a do it all knife that's a knife I'd ditch the stainless steel requirement, and go to a hard use carbon steel fixed blade: The knives listed below have traditional points that will still break if you aren't careful when prying, but will be far tougher than almost any stainless steel blade heat treated to the same hardness.
Ethan Becker is the man who popularized the so-called "sharpened prybar" concept of a survival knife, so why not start there:
BK&T ESEE KA-BAR Neck Knife
Becker BK-16
Then there are the ESEE knives:
Izula and Izula II in your choice of blade and handle colors
ESEE 3 - Great all around fixed blade, also available in several colors.
Last, and certainly not least, there's Ontario Knife Company:
RAT-3 which was in production before a schism lead to the ESEE knives
Ranger Falcon - Made from super tough 5160 carbon steel.
Hope that helps.
