    lately I've been interested in getting a Fallkniven F1. Theres just one question I have. What is laminated VG10 and how is it different from regular VG10?

    G'day ToxicEdge

    Welcome to the forum.

    Laminated VG10 has a core of VG10 steel that is sandwiched (laminated) between an external layer of 422j2 steel. It gives added lateral strength (about 25% stronger than straight VG10) to the blade whilst still retaining the edge holding characteristics of the VG10 edging steel.

    Vg10 steel is just that, straight VG10.

    Hope this helps

    Kind regards
    Mick

    BTW If your interested, the Fallkniven website shows details of break test they comissioned to test the strength of their blades.

    Why we are on Q&A for steel's i thought i ask, what is the difference between Laminated SGPS and 3G steel. The U2 is the former and the TK1 etc has the latter printed into the blade. But there isnt any difference is there? the Hardness is the same... So why they got different names? or is there a difference?

    And while im at it, the forming process of both VG10 and 3G, how do they differ and what are they? Im guessing VG10 is either put into molds molten or continually bend and folded to form the steel? But how does powdersteel work? Some kind of fusion of powdered steel?

    Cheers

    Craig.
    Hope for the best and plan for the worst!

    Laminated SGPS (ie U2 model) has the SGPS as the edging steel and 420j2 as the external laminate steel (BTW I noticed a typo in my previous post. Its not 422j2 but 420j2). The 3G steel has the same edging steel as the laminated SGPS (ie SGPS) but has a different external laminate of VG2 at 59RC. I guess the name 3G comes from the addition of the one G in the name SGPS and two G's in the VG2.

    Sorry I can't answer the second part of your question as I don't have enough metallurgy knowledge to comment on how the powdered steel is actually manufactured.

    Hope this helps.

    Kind regards

    Hey Mick.

    I always wondered about the hardness of the outer layers.
    How do you know VG2 is 59 RC?
    Is it the same RC as VG10?
    And 420j2, are they softer?

    thanks

    I remember Peter mentioning VG2 being 59RC some time ago in another post.

    Yes VG10 has the same Rc of 59.

    I believe the 420j2 is softer (i don't know the RC of this) as it is certainly easier to scratch than the VG2.

    Hope this helps

    Kind regards

    The 420J outer layers are at 54HRC if i remember correctly.
    The 3G means that it's the third generation.

    The 3G-steel (SGPS)holds it´s edge about 4-5 times longer than VG10-steel (same edgesteel as in Lam. VG10, wich also uses 420j2 as laminate). And with the different laminate in 3G-steel,VG2, (than ie U2-folder, wich has 420j2 as laminate) it´s also more resistant to rust.

    Hope this help?
    And if it´s wrong, feel free to correct me.


    Take care!
    So conclusions:
    Lam. VG-10 (ie A1) Edge:VG10 Lam:420j2
    SGPS (ie U2) Edge:SGPS Lam:420j2
    3G (ie T1) Edge:SGPS Lam:VG2


    Take Care!

        In response to Kni_Lig

    correct (although Englander was comparing lam SGPS to 3G ), but I don't know if VG2 is more resistant to rust than 420j2.
    Getting rust on 420j2 is already difficult
