Mustad manufacture and extrude their own wire on site in Norway to ensure quality is never compromised in these clips. It's a quality assurance that is hard to find elsewhere. Operation of these clips is incredibly easy. Simply twist onto the lure's tow point and then when a lure change is necessary, reverse the process. You can do this with your eyes closed after only a little time with these incredible clips in your hand. Even under extreme pressure, the clip will not fail. In the event of too much pressure being applied, such as when a tackle retriever is being used, the Fastach Clip will only tighten its grip on the lure's tow point. This means every fish hooked can be landed! You just do not get that with other clips. The Mustad Fastach Clip is available in sizes from 0 (around 7kg breaking strain) all the way up to the ultra-strong size 5 (around 75kg breaking strain) and will suit everything from the estuary and freshwater angler right through to the serious bluewater angler. Mustad quality meets innovation in the Mustad UltraPoint Fastach Clip.
