    Re: How to bend a French Grip (and not break it)

    To actually answer his question...

    It is not only common, but preferred to bend the tang for the use
    of a French grip. Of course, I discourage extremes in this -- and
    this is what I discern from his story -- for the dual reasons of
    retaining the only strength of the tradition French grip (and school
    of fencing) being control of the weapon, and the fact that there
    is less change of being the tang!

    First of all, do not try to bend the tang at the transition from
    forte to tang; the stress-riser of the machined area often will
    incur breakage. The correct place to bend it is just aft of the
    transition of the square to round tang.

    Secondly, use a blowtorch to warm the metal before bending; I assume
    that you are using a standard, non-maraging blade -- these react
    differently to heat and bending forces. No, I do NOT mean heating
    it up to red-hot or anything near the eutectic temperature of LAHC
    (Low-Alloy High Carbon) steel which is used in many blades, which
    would compromise its heat treatment. A temperature of 250 to 300
    degrees is more than sufficient, and will protect the metal (assuming
    no flaws) from breaking when the radius of bend is gentle. The
    temperature generated by vigorously moving the blade between a
    terry-cloth is sufficient to heat up the heat to beyond 200 degrees,
    but you will not be able to do this on the much shorter tang.

    A bend of 15-25 degrees downwards and a similar bend leftwards
    (assuming right-handedness) is optimal for the French tang -- but
    no more.

    BTW, I've tried most orthopaedic grips, and have been appalled by
    almost all of them -- the Belgian Grip is an utter abomination (but
    I _do_ realise that there are several manufacturers haaving subtle
    design differences). The American Grip is no better, and the Russian
    is hard to retain in the hand with vigorous fencing -- but then so
    is the French, which is the only reason I thought to need to switch
    when fencing competitively. I currently use the Spanish Traditional,
    although I personally feel that the German Grip is technically the
    best design for the criterion of finger play.

    get me started about the nonsense and delusions prolmugated by armourers
    concerning the legality of the Spanish Traditional...

    I am so fed up with the style of fencing that an unpommelled
    orthopaedic grip by necessity devolves into, and the concurrent
    laziness of referees who show no evidence that they've even bothered
    to read the rules, and are consequently inurred to this style of
    fencing (point threatening the floor one-half the time, the referee's
    nose the other half), that I have "put my money where my mouth is"
    and am nearly done on a design for a pommelled orthopaedic grip that
    I feel addresses the relative advantages and disadvantages of both
    the French and orthopaedic grips.
    Time will tell...

    While there may be some value in this approach I've never seen
    an armorer or vendor do other than apply a the handle hole in a
    crescent wrench at the transition from forte to tang. That said
    I did inherit a blade which had had the tang broken off at this
    point - I cut the tang and 1/4 inches of the blade off a broken
    weapon and welded it on and it's served admirably for working
    with the dummy.

    I am quite curious about this as I indicated earlier I've never
    seen anyone go to this much trouble when putting the desired bend
    in a blade's tang. What I've witnessed frequently and what I do when I
    setup my own blades is to take a large crescent wrench and put the
    hole in the handle over the tang - blade mounted in a vise - and
    then bend the tang albeit slowly.

    Does anyone else go to the trouble of heating the tang? Not to
    imply that this is wrong or bad practice.

    As a part of your effort I would suggest inquiring about what is
    legal in grips. In epee most of the fencers I've met who use the
    french grip do so that they can "POMMEL" it, i.e. slide it forward
    until the pommel is in the palm of the hand thus giving them a
    couple of inches of advantage in the extension. I believe this is
    illegal for orthopedic grips into which category a hybrid grip
    would probably be placed. So my understanding is that your
    design must be such that a fencer cannot pommel it.

    Re: How to bend a French Grip (and not break it)

    The tangs of blades are generally annealed so that they are readily bent.
    Lammet blades from the early-to-mid 90s sometimes had brittle tangs that
    were
    prone to snapping when bent, but otherwise breakage at the tang is of
    little concern for foil and epee blades, and I've never known any other
    armorers who heat tangs to bend them. Aside from the above mentioned
    Lammet blades, I've never had a blade break at the tang while putting a
    cant into the tang.

    Thank you for your responses; it is indeed "overkill" to _necessarily_
    heat the tang before applying the bend, but I wanted to be comprehensive
    in my offering, but I still do recommend that tangs not be bent at
    the guard detente. I am an old enough fencer that I remember well
    the hand-made, case-hardened, high-carbon steel blades that were
    available 15+ years ago. The strength of these blades were in the
    outer case-hardening, and when a flaw developed in this thin veneer,
    they would snap spectacularly. On the other hand, the annealed tangs
    were _too_ soft, and either didn't take a permanent bend, or developed
    a "soft" failure. Thankfully, these days are over with LAHC alloy
    blades. You young'uns don't know how good you've got it

    http://groups.google.com/groups?q=gr...rQ.com&rnum=43

    I use the blowtorch method, however, because with many blades (10
    or more), the bother of taking out the equipment, and the 5 seconds
    of applying the heat per blade, more than makes up for the 1 in 50
    blades that will break, that I will have to buy for the club. This
    cannot be any harder than dragging out a welding setup! I've never
    heard of such a thing, and the only time I've considering it is
    when I broke the tang of a rapier blade in some vigorous choreographed
    duelling!

    What _really_ takes up some time (and mental energy) is describing
    the process of turning 35 inch blades into 30 inch blades by cutting
    and forging anew the tip finial...

    Thank you. I don't think I adequately emphasized the situation of
    needing by practical necessity to abandon the Spanish Tradition
    grip merely because tournament armourers are arbitrary and ill
    informed. I, however, have read the rules -- many, many times (I'm
    a qualified referee) and the six subparagraphs of rule m.4 are quite
    sufficient to determinately assess legality.

    Pommelling is indeed only sanctioned for the French Grip and no
    other -- and this grip position cannot be made by "throwing forward"
    the foil in a lunge. The contested legality of the Spanish Tradition
    is predicated on the supposed ability for the hand to adopt another
    position on the grip which places the thumb more than the maximum
    two centimeters from the guard. A hypothetical offset, pommelled
    grip has _less_ of this concern, being that there is a "cutout"
    that fits the palm and fixes the hand.

    The pertainent rules are:

    Rule m.4 subparagraph 6:

    If the grip (or glove) includes any device or attachment or has a
    special shape (orthopaedic) which fixes the position of the hand
    on the grip, the grip must conform to the following conditions.

    (a) It must determine and fix one position only for the hand on the
    grip.

    (b) When the hand occupies this one position on the grip, the
    extremity of the thumb when completely extended must not be more
    than 2 cm from the inner surface of the guard.

    I hate to sound over-dramatic, but if my grip is made illegal by
    the USFA or the FIE, the French traditional school of parry-riposte
    fencing will be permanently damaged; the problem is not flicks, or
    EVEN bad referees, but the physics of leverage -- if athletic, male
    fencers cannot appropriately manipulate a point-heavy, unpommelled,
    electrical weapon in absence-of-the-blade parry-riposte fencing,
    what chance do females or young fencers have? French grips are
    simply not practical for fencing against orthopaedic grips, except
    via the technique of "threatening the floor half of the time, and
    the referee's nose the other half."

    Re: How to bend a French Grip (and not break it)

    While I agree with you that completely banning pommeled orthopedic grips was not
    the course of action I would have taken, it is not the case that armorers who maintain
    that the pommeled Spanish grip is illegal are ill informed-- the wording of those rules was specifically
    targeted at the Spanish, Gardere, Dos Santos, and other such grips. They are not permitted--
    that is the entire intention of the wording in m.4 (since the FIE wrote and owns the rules lock, stock and barrel,
    their interpretation of them is the only one that matters). If you were to try to submit a weapon with the
    Spanish grip to control at a World Championships, it would be rejected out of hand by the SEMI
    officials in charge.
