The 1251 Twisted Fiddle is a true Zircon block with a unique twist. Its slim shape slides easily along the purchase system it inhabits, to remain upright where conventional double blocks tip, twist, or tangle. A fiddle is a better choice where the line moves in uneven sequence around the two Zircon sheaves.
