B... Luthiers (21st. C.)

Edmund Baccani comes from the Philippines where he learned luthiery and uses the nickname Nice? he was the luthier behind the D&D brand, (D&D stands for Daniel and Doris who ran a Ukulele shop in Lahaina, Maui). This apparently started in 1995 and they appear to have stopped production in 2009? I believe Edmund then went on to make Ukuleles just branded with his own nickname. I have seen some similar looking Ukuleles dating from 2009 but branded as Nice Ukuleles

From Nanakuli, Hawaii. he learned the craft working for G String and Kanile'a. before leaving to start his own firm in about 2007 with his brother Kimo (who looks after marketing and the like). He uses the brand name Wai'olu and makes make Soprano, Concert and Tenor Ukuleles plus any custom work that comes along

Bill Barnett from Honolulu brands his work as Hana Lima Ukuleles, (Hana Lima means something like Hand Made in Hawaiian), and started making them before 2004.

Based in Sproat Lake, British Columbia he has been a member of the Guild of American Luthiers since 1997 building acoustic Guitars under the name Martin Beck, (as Martin van Humbeck just doesn’t fit on a headstock"). Though acoustic Guitars are the main output he also builds Resophonics, Tres, acoustic Basses and Ukuleles. On his website he lists Tenor and Baritone scale Ukuleles as an option and says "Sopranos are just to tiny". One feature of his Ukuleles is the distinctive ornate sound ports he puts on the side, another is the slightly spiral rosette shape.

From St. Thomas, Ontario, Marc Beneteau is largely self taught and started making Guitars in 1974. He still makes mainly Guitars but has made a few Concert and Tenor Ukuleles over the years.

Peter Bermudez used the branding Hai'kuI and I believe he started some time in the 1970's, in Kaneohe, Oahu. He was a full time luthier and must have been bigger than a one man outfit because Joe Souza who founded Kanile'a was his apprentice and learned the art of luthiery from him in the 1990's. I don't know when, (or if), he died.

He marked his work with a sound hole stamp or label and was very fond of Lili'us 

Stewart "Sonny" Black is based in Osoyoos, British Columbia and he does stringed instrument repairs and design. He was taught luthiery by Michael Dunn in 1989 and he makes all types of chordophone including acoustic and electric Guitars, Mandolins and Ukuleles under the banner of Blacks Guitars. I am not sure if he is still in business as his website stopped working in 2015? All of the Ukuleles I have seen that were made by him have been Concert scale so I don't know if he only made Concerts? What he did make though was a triangular Ukulele that was clearly influenced by the old Northern Canadian School Ukuleles, that he calls the Tri-Style.

From Sydney, Australia and largely self taught, he makes koa or mahogany Sopranos he calls the Iz and the Duke. He started the brand Freshwater in 2011.
