• Similar results are noted with the brass agraffe used by Sohmer into the 1930s.
• The Stuart and Sons Agraffe device is used to couple the strings to the bridge and soundboard structure.
• Worn string holes sometimes cause a buzzing sound which can be corrected by filing inside the agraffe string hole to remove the imperfection.
• They are sometimes difficult to remove and a broken agraffe usually requires a lengthy repair ( especially if they are broken into the plate ).
• The agraffe defines the string's speaking length ( frequency ), containing the reaction forces produced by bending the strings as they pass through it.
• In 1866, Wm Knabe & Co . introduced their " agraffe treble " with agraffes threaded into a heavier piece of brass instead of directly into the iron frame.

• In modern pianos, the same basic principle is followed : the contact point for the vibrating length of the string that is close to the hammers is either an agraffe or the capo d'astro bar; these devices pull the string in the direction opposite to the hammer blow, just as in Cristofori's original arrangement.
• Hugo Sohmer marketed the first modern " bijou, " or " baby grand " piano, built with a symmetrical case design which he patented in 1884 . " Only five feet long, " these pianos were advertised as " the smallest grand ever manufactured, " having " great power and volume of tone, together with the tone-sustaining quality and elastic touch heretofore only found in the concert grand . " The company also patented improvements in agraffe bars and actions in 1882, and in 1887 an agraffe for a quadruple strung " reverbation scale " and a pianissimo pedal in uprights, and bridge agraffes in 1890.
