We gave the Cutthroat(TM) oar blade its scooped shape so you can get the most out of your stroke, no matter the river conditions, and concentrate on what lies ahead. Greater submerged surface area allows for maximum propulsion in low water conditions. The asymmetrical shape is especially popular with fishermen maneuvering in late-season streams, when water is low but the fish still bite. With the Cutthroat(TM) shallow water blade, you'll be able to put your boat exactly where you want it and keep it there. Made in the USA. Compatible with the SGG(TM), SGX(TM), X Wound(TM) and Streamlite(TM) oar shafts.
