If by 'hard use' you mean prying, batoning, chopping, and digging among other tasks. Sr101 (52100 with the busse heat treatment) will retain a better edge and is display more toughness than any 10 series steel. This is simply due to the properties of the steel. Plenty of other steel's are tougher than 52100, and others will hold a better edge. 3V comes to mind... The only limiting factor is the size of your wallet. All steel's are a compromise in the end. Trick is to find a good steel and heat treat that meets your needs.
That being said, I've owned a couple of the older Camilus Beckers and thought they were good knives. And despite my best efforts, I've been unable to notice any appreciable wear on my Becker Necker's bottle opener. Love that thing... it's so cool. 1095 is a fine steel. I'm certain that Beckers are a very good value for a working man's buck. Frankly most folks won't ever push a knife to the point they will notice the difference between the two steels.
But I do. I beat the snot out of mine. And for that reason, I spend a bit more because I like to know my knives can be pushed hard... and not fail.
Take a look at the Scrapyard knife co's website. It's the same great steel that Swamp Rat uses but priced a bit less. http://shop.scrapyardknives.com/cate...6?categoryId=4
Good luck with your choice.
