Dear Martyn and Martin
It is true that Carlos' original message was slightly ambiguous,
but I have asked him to clarify this question, and he tells me that
between KFN33 et KFN91 the strings are still simplex monofilament, it
is only below the diameter of 0,95mm (KFN95) that strings are
composite. He goes on to say that in his experience the lowest limit
for lutes is KFN140.
Carlos sends you his friendly regards
Best wishes
Anthony
PS If you have more detailed questions, I will try to ask them to
Savarez.
Thank you for this Martin and Anthony. These strings are interesting as
a further alternative to loaded, wire wound and the 'spring' string;
especially for those with a large number of instruments to string.
I looked into these Saverez KF strings some time ago (are you sure
they're 'new' out?) and had reports at the time that they were simply
PVF(carbon) strings like any other of the same ilk. I'd be grateful for
any clarification you can
offer.
Martin, you say they only become multi strand above 0.95mm dia but in
Anthony's message he gives someone using thinner KF strings with the
implication that they are these new multi-strand type. 'an example of
the stringing he uses on a lute or 7c Vihuela : g' KFN33 - d' KFN43 -
a KFN52 - f KFN66-33 - c KFN84 - 43,5 - G KFN 112 - 57 - F KFN126 -
62.' Is it possible that the 'new' aspect of these KF strings are that
Saverez now makes these multistrand strings at smaller diameters?
What's the signoficance of the N in KFN? Does it mean new/nouveau type
of KF strings?
The Saverez website is next to useless only giving marketing blurb and
lists of available sizes but says the strings are made from 'composite
fibres' which again implies that all sizes are multi strand. They also
make the claim that they are new but perhaps they simply haven't
updated an
old website?
ALLIANCE KF COMPOSITE, Strings for harp
A real innovation! This strings are manufactured from composites fibres
A production which requires fine and sophisticated technologies that
only Savarez could implement until now.
Thanks to the technologies, Savarez can produce strings which
geometrical qualities are perfect and which resist to the tensions
required by the harp. Many years of work and a focusing of complicated
technologies were necessary to obtain such a result.
A long work on the molecules, some molecular relationships and the rate
of "cristalinity" allow Savarez to obtain an elongation and an
elasticity identical to the ones of the gut.
The density of these strings is extremely close to the one of the gut,
so the comparison takes more value. So though gut strings still are
very popular, Alliance KF strings have a perfect alternative sound
for
those who wish to take profit of gut sound and synthetic strings
advantages.

Dear All,
I have been using these KF strings for some years. The smallest
diameter is .95mm, but this is the equivalent of a gut string of about
1.07mm. The one I use is "KF95A", but I think the "A" just refers to
the fact that it is a 2m length. It works well as a 5th course on a
renaissance lute (with an octave - I have not tried unison). It looks
more like a gut string, opaque rather than clear. I have not tried the
thicker strings, but it seems that it might be worth a try - I think
Jacob Heringman may have done so. I think the next size down is .91mm,
but it is a plain monofilament PVF string. I think some people are
using them for a unison 5th course.
Best wishes,
Martin
