About four years ago, Practical Sailor tested a bunch of anchors of hold strength, resetting ability, versatility, etcetera. The one they chose as best for all-around use, based upon penetration and holding endurance in various bottom types was an English-made anchor called the Spade
(which is now also made in the USA). It also came in 3rd in resetting ability.
It's kind of a chisel-point plow-type anchor. I bought two of the S-40 galvanized models.
