For what it is my Gerber Profile in 440A (older one from Wally World for $17) is a decent knife for casual work. Love the feel, shape, and balance. I'd like to have a custom made of better steel to those same design specs. For the cost of the knife for casual use it's okay. Not great, not heavy duty, just a usable cheap knife. Gerbers today and for the last many years are not the Gerber of old.
However, it ain't my first or even 10th choice for an only knife in the outback sort of blade. I could make it work as long as I could makeshift some sharpening material or have a little diamond paddle on me. But I'd take many other knives first.
Of the three mentioned anything Becker and nothing Gerber. Especially anything marketed for the hard use/military/survival market and especially if it's the Bear Grylls line.I've found in things like knives and hunting level break action pellet rifles, if it has some celebrity name on it, they cheaped it out somewhere. Get the better version without the name for the same price or less.
The LMF is probably one of the more capable of the modern Gerber line, but for the money there is just much better available. That and I have come to really dislike the partial serrations on a knife. If I want serrations I'll carry a fully serrated knife like I did a small SOG lockback in a horizontal pouch alongside my SAK Champ when I was in the Army. The SOG was specifically for cutting rope.
Don't forget a lot of those Marines packing 1095 carbon steel Ka-Bars in the Pacific Theater on those islands. They seemed to manage around salt water just fine.
