The Thomastik-Infeld KF110 Classic S Rope Core set is an innovative hybrid string set engineered specifically to bring acoustic steel string tone, projection, and brilliance to classical and nylon-string guitars. Handcrafted in Vienna, this ultra-light .010–.038 set uses highly flexible rope core steel architecture to keep overall playing tension comparable to standard classical guitar strings, allowing players to enjoy crisp acoustic response without risking soundboard or bridge damage.

Unlike standard steel strings that overload nylon-string builds, the KF110 combines a brass-plated high E with stainless steel flatwound B and G strings, paired with polished nickel flatwound bass strings. Fingerstyle players, folk musicians, and concert guitarists across Australia choose the Classic S KF110 for its silky-smooth playing feel, reduced fret wear, suppressed finger noise, and unique acoustic sustain that bridges the gap between traditional nylon warmth and bright steel articulation.
