OK I need some input from busse owners, Why should i spend big bucks on one of these things, is the steel really that great?
In a word, yes, it really is that great. The edge retention, as others have said, is not the best, but it's pretty good. On a par with all but the hardest steels optimized for edge retention above all else. I have to warn you, though, that you should either keep the factory grind angle, or use a convex grind (some Busses come with a convex grind) to maximize edge retention.
That being said, INFI is surprisingly easy to sharpen. Easy like on a par with 1095 IMO. I found that, unlike most other super steels, INFI sharpens just as easily with an India stone as with a diamond hone. If you're worried that the edge may not last as long as you want in the field, carry a DMT DiaFold sharpener (double sided diamond hone that weighs nothing).
The factory edge tends to be "toothy". For most chores, they slice like a demon, but won't shave hair if that's your measure of sharpness. However, that all changes when you keep the factory grind angle (20 degrees per side) and just polish the edge. Then they will shave hair and make great fuzz sticks from wood.
It seems INFI is optimized for toughness, and from what I've seen some other steels come close, but none exceed INFI at this time. Thinner Busses have been broken, but it's usually a tip that goes, and it was doing things like prying open car doors. I don't see anything you'd do in the woods breaking a knife made of INFI.
I am looking for a 6 or 7 inch blade for just about everything from a hunting knife to shelter building if needed. I am looking at a hell razor, what is this blade designed for in your opinions? The blade is 3/16 thick, i like the idea of busses 1/4" or even 3/8" thick blades.
Well, at first I couldn't see where INFI would be so great as to justify its cost. But I had recently come out of a partial amputation surgery and decided "to hell with it" I'm getting what I want instead of driving my life by what I need. I always thought the HellRazor was the sexiest Busse knife available (and still do), so I bought one off the exchange.
The blade is balanced like a fighting blade -- very nimble, but also easy to control. With the spear point and swedge, it's a fine stabber. My first thought is that it wants to draw blood. Turns out, it's a great hog hunting knife.
It also makes a great all-round knife in the woods. IMO, the answer to the "I only want to carry one knife to do everything, what size should I pick?" question is a 6-7" knife. Here's a little review I did of using the HellRazor and the Boney Active Duty (BAD) for some bushcraft work:
A Little Hell Razing
I've since also picked up a CGFBM. It's a big knife that really should be paired with a small blade. Even though it's 1/4" thick, the width of the blade makes for a fairly slim taper from edge to spine and that produces a knife that both slices and chops well.
If you want to go all Busse, a CGFBM (or most any other Battle Mistress) and an Active duty, Boney Active Duty, Game Warden, etc make a great pair.
You're also in luck as right now Busse is offering the Bushwhacker Battle Mistress at the factory site. It's a 3/16" spine (.220" for the LE) BM, that should be one of, if not their best camp knife, as it will be a wicked slicer and still be able to chop. Best of all, you don't have to pay aftermarket prices if you buy it while it's still offered.
