Horseshoe Nail
The horseshoe-style pipe nail has a couple of distinct advantages over the standard model. First, it's a bit heavier, which allows you to use the weight of the nail to tamp, without having to apply pressure, which can make for a harder draw. They also have a slimmer "spoon", which will make it easier to get at stubborn scraps in the chamber and to get down into the tobacco, if you need to loosen things up.
*MSRP stands for "manufacturer's suggested retail price," which is the price recommended by the manufacturer or exclusive distributor for retail sale. This suggested retail price, also referred to as the "list price," serves as a guideline for pricing the product.
