All Dr. Slick Clamps are made with 410 Japanese Stainless Steel with a Rockwell hardness of 42. Designed to handle all your streamside tasks like hook removal, barb crushing, and closing shot with no finger loops! This series was designed for angling in cold weather where gloves or mittens are the norm, or for tangling with big fish. If youve ever had your knuckles mashed by a powerful fish, the beauty of these clamps becomes apparent. Excellent for salmon, steelheader, trout and saltwater. Simply squeeze the clamp all the way through the ratchets to release. To close, squeeze until the ratchets lock. This one-hand wonder is spring-loaded, has a wrist lanyard, and can easily handle all streamside tasks.
