Brazil wood bows are considered student level bows. The wood is decent, good enough for beginners and you still get the warm sound that most wood bows produce. Ipe wood is considered to be similar in structure to Pernambuco wood. This means you can get a quality Ipe wood violin bow for half the price of Pernambuco, but it is still high quality. Ipe wood isn't endangered, so the price is much more appealing to bow makers.
