Sailrite snap tool: Anvil - We bought this a few months ago from Sail Rite and then remembered that we already had another one which we'd bought a few years ago, and since we don't need two, our loss is your gain. The concave middle is used to hammer the snap into your marine fabric socket/barrel/gypsy stud while protecting the thin metal from becoming kinked. These sell new for ~$16 plus tax and shipping, we're asking ~half of retail. New, never used. Price is firm, please no haggling. Cash only.
