I found this knife on Aliexpress: and say the claimed HRC of 62 vs a average HRC of 58-59 of 8cr13Mov http://m.aliexpress.com/item-desc/1893958673.html so any input good or bad please feel free to post them and your reasoning.
I doubt that knife has a true D2 blade, but likely it is Chinese marketing “D2”, which would be more like an equivalent type 400 series stainless steel - 3CR13MoV, 7CR17MoV, or if you are lucky 8CR14MoV. Blade quality is more than the metal type used, it is also geometry and heat treating, and D2 is known to be a difficult steel to properly heat treat (D2 is a tool steel). Frankly, I would not trust a no-name Chinese manufacturer to get the D2 heat treatment correct for blade use.
What do you mean geometry wise ? Are you referring to the shape of the blade or the alignment of the steels basic elements prior and during heat treatment and solution quenching and possible war page ? And I was hoping but I hate to say it I think you’re right about this blade .dang since I left aviation I no longer have a way to proof it.
Blade geometry = the grind type and angle(s ).
That is definitely not D2, with chineese knives steel type is more exaggerated than lumen numbers with chineese lights. If your lookin at any chineese knife that claims anything other than 440c or 8cr13mov (or similar) pretty much blow it off right away.
9Cr18MoV knives one a Harnds ck6015 Viper and a Schrade 501 HS which sharpen completely do and hold an edge much better than my Sanrenemu s enlan s or even my Ganzos but yeah I think that D2 tool steel on that knife we I just may have lost 20.00$
