Being the frugal sort in many matters, I have been contemplating switching from precision groung O-1 to 1095 for my small stock removal hunting knives. I also want to get better temper lines.

1. What is the difference between HR (hot rolled?) and CRA (cold rolled and annealed?) Is the HR not annealed? Will HR 1095 grind harder or easier than O-1?

2. How should performance differ? Any recommendations on changes in heat treatment? I do my own with torch and oil.

I may also try some 1084 instead of 5160 for some of my fighters and bowies, any commets?

Well - let me modify my question. Has anyone had any bad experiences gringing HR 1095 and 1084. Any comments on really bringing out the temper lines?
 
Hot rolled is as it comes from the forging roll, it will have a rougher finish and more scale than the cold roll the cold roll is hot rolled with the addition of, being cold rolled. This step refines the grain and finish of the steel.

Are you forging or grinding? The cold roll will have a better surface to start with and thereby less grinding, cold roll will have slightly smaller dimensions than hot.

If you are forging it would not matter as you are going to whack heck out of it anyway.

My conjecture about the hot rolled is that it is probably normalized, from coming out of the roll "hot".

The cold rolled would have been annealed after rolling to remove the stress from the cold roll operation.
 
Yes I will be grinding, not forging. I am wondering how hard or easy the HR 1095 sold by Admiral or Koval will be on belts compared precision ground O-1?
 
i use stainless steels, and i know they are tougher to grind than 1095, based on that i'd say that it will be pretty easy to grind, you might not even notice the difference between that and o-1.
 
Hi I am just starting to making knives
make knives,and I have found out that carbon steel as a whole are eaiser to grind than
stainless, I have ground O1 and 1095 and
can't see any diference in there grinding
the only thing I can see is the carbon throw alot more sparks and some even land on the floor and will burn the dust that collects on the floor,good old carbon burning
I think the carbon blades are much eaiser
to work with and the steel is cheaper the
only down fall is the rusting if it were not for that I would make all my blades with 1095
just my thoughts on the matter
 
The 1095 take a faster quench time. I perfer the O1 or 1084 . 1095 has about two seconds to get from the aus temp to the oil or water.. The others have more time..
