420HC vs S35VN.

The PakLite 2.0 Field Knife in each steel

The PakLite 2.0 Field Knife makes this choice easy to see, because the two listings named here give the same blade length. The Buck 631 PakLite 2.0 Field Knife gives a 4 inch stonewash 420HC blade and a black glass filled nylon handle. The Buck 631 Paklite 2.0 Field Knife Gr gives a 4 inch stonewash S35VN blade and a green canvas micarta handle. The two distributor texts share an 8.25 inch overall length, a full tang, a lanyard hole and a black polypropylene sheath, and the USA is the origin on each listing.

The S35VN listing costs more than the 420HC one, and the distributor texts show two differences to set against that step: the steel and the handle. For the steel half of the decision, the question on a fixed blade that works outdoors is which failure you run into more often, an edge gone dull or a blade that spots and nicks, and whether you sharpen as you go or leave it until the work is done.

Both Alpha Hunters give a 3.63 inch drop point

Buck's Alpha family makes the same split with more changing around the blade. The Buck Alpha Hunter Select Gray gives a 3.63 inch stonewash 420HC drop point, a gray glass filled nylon handle with a black Versaflex inlay, a full extended tang and a black polyester belt sheath, 8.38 inches overall. The Buck Alpha Hunter Walnut gives a 3.63 inch satin S35VN drop point, a checkered walnut handle, a full tang and a brown leather belt sheath, 8.13 inches overall. The Buck Alpha Scout Walnut carries S35VN on a smaller 2.88 inch satin drop point, 6.63 inches overall, with the same checkered walnut handle and brown leather belt sheath.

Between the two Alpha Hunters, the finish, handle, sheath and overall length all change with the steel, and the Walnut costs more than the Select Gray. When the handle and sheath you want come attached to one steel, the steel is the part to understand rather than the part that chooses. Either way, its ratings describe what you are accepting along with the knife you picked.

Dulling is the failure S35VN is rated against

S35VN's case is its edge, rated very good. On the same line, its record notes that the niobium carbide addition gives "a finer, more uniform carbide structure than S30V", from a recipe of about 1.4 percent carbon, 3 percent vanadium and 0.5 percent niobium. On a fixed blade, a very good edge rating means more cutting between sharpenings, which makes the S35VN listing the one to take if your edges usually go dull before anything else goes wrong.

The 420HC stainless record rates its edge retention modest by modern standards, then adds two things that matter to someone who sharpens as they go: reliable, and very easy to sharpen. A 420HC blade asks for the stone more often and gives its edge back quickly, so a small stone in a pack turns a dull edge into a short pause. The S35VN record makes its claim on the other side, in how long the edge lasts, and says nothing about how the steel takes a stone. If you touch up an edge in the middle of the work, 420HC's rating is written for you; if you would rather sharpen seldom and at a bench, S35VN's is.

Toughness rated against S30V, not against 420HC

The toughness line needs a careful read. S35VN's record rates its toughness as improved over S30V, which is a comparison with S30V, not with 420HC. 420HC's own toughness rating is very good, a standalone grade, and no published figure here sets the two steels side by side, so neither record ranks one tougher than the other. How S30V itself fares on toughness is the business of 420HC vs S30V.

On corrosion the records are plain: excellent for 420HC, and good for S35VN steel, similar to S30V. That gap is the one a fixed blade meets when it is stored before it has dried.

So let the failure you see most make the choice. If your fixed blades usually come back dull, S35VN's edge rating answers that. If they come back spotted, or nicked from knocks, and you sharpen as you go anyway, the 420HC listings named here answer it, and each costs less than its S35VN counterpart.
