The pear shape is perhaps one of the most common sinkers used by boat anglers today. Designed with the bulk of the weight being situated at the wider base, tapering slowly upwards to a moulded-in eye or swivel, this style is perfect for all manner of fishing situations.
I use them in sizes from 2oz up to 12oz, which covers me for lure fishing, drifting for plaice over rough ground, fishing at anchor for smoothhounds or bass, and even for tope or conger eels in deeper water.
Definitely a must-have in my tackle box.
