I keep hearing this, but is it demonstrably true, or just marketing that has been accepted as true by the knife community?
It is my suspicion that folks just tell themselves it is true to reconcile their love for Buck knives with the steel snobbery they have when it comes to any other brand.
Is it possible that nobody else has figured out how to heat treat it? What if it turned out that 420hc was just fine for everybody all along?
Not being contrarian here, but genuinely curious.
Buck uses BOS heat treat on all their domestic blades. I don't know if they do on the imported blades, but my
guess is they do on the imported 420HC blades. It wouldn't be difficult to use the same procedures, temperatures, and times, after all.
I don't know if Mr. Bos developed a heat treat for the 420J2 blades used on the imported 37x and 38x slipjoints.
I do know I haven't had issues with my 371 stockman's and 389 canoe holding an edge, or had to sharpen them more often than my Case Sodbster Jr. with a True Sharp blade.
Buck doesn't put the BOS heat treat etch on the 420HC blades though.
Paul Bos was head of the Buck heat treat for a "few" years.
BOS heat treat is considered the "best" by a lot of folks in the cutlery industry, and consumers who care about such things. Believe it or not, most consumers don't know or care about the different heat treats used for each steel. If they think of the heat treat at al, they just expect the manufacturer to "get it right".
Buck does run their 425HC one or two points harder than Case runs their "Tru Sharp" 420HC. Which I understand "makes it a totally different steel" insofar as performance goes.
Of course the same can be said for other steels. D2 for example, run soft does not perform as well as D2 run a couple points higher. (Yes, the softer steel
may be considered "tougher" but it won't hold an edge as long.)
In normal use Buck has a reputation of holding an edge longer than Case, Schrade+, and Leatherman 425HC blades. On the flip side, since the Case and Leatherman blades are a little softer, they are "easier" to sharpen using the same method and equipment.
To be honest, Case and Leatherman blades will do the job just as well, but will need sharpened a little more often.
From experience I can tell you a Buck 110 with a 420HC blade can peel and field dress 3.25 to 3.5 whitetail before it needs stropped or sharpened.
An Schrade+ Old Timer 6OT or 7OT can peel and field dress 2.5 to 3 whitetail deer before it needs stropped or sharpened.
"Schrade+" was 440A or 420HC. I believe they used both over the years. By calling is "Schrade+" (or "Tru Sharp" in the case of Case) they don't have to specify which stainless steel it is. I believe Case and Schrade USA ran their blades at the same hardness, or close enough it didn't make any difference.
From a marketing standpoint, it would make sense to specify 440C and "higher".
