The first question is what is your boat, and how much does she weigh? The claw/Bruce type anchors are decent setters but offer relatively low holding power and should to be up sized at least one size when compared to some other anchors..
Oh, and yes, the knock offs do and can break.. The original Bruce was heat treated and many if not all of the knock offs are just plain cast..
This is NOT my photo but would love to give credit to whom ever took it. If anyone knows please let us know..
