African Blackwood scantlings from old clarinet tonewood stock, surely stored for 10 -15 years. These are the last availables. Replenishment unlikely.
A tip for the success of your work: Grenadill, like almost all very hard and dense types of wood, especially with thick cross-sections (from approx. 60 x 60 mm), tends to crack on endgrain surfaces in dry and warm rooms with low air moisture values; you must expect finest cracks to form during processing. Please do not expose the wood to sudden and strong temperature and humidity changes and protect the end grain surfaces with wax or a thin coat of white glue.
