The Summit Colosseum Thumb Screw Bankstick Stainless from Summit Tackle is part of the Cobalt Black range, which uses a unique hardening process on military grade stainless steel to create a hand finished product. The thumb lock screw features a 200mm approx flat milled down the inner section, so when used with a Buzz Bar, this design eliminates twist. The bankstick is easily recognisable by its distinctive Colosseum fluting and ergonomic thumb screw, and is produced using the finest 1/2 inch diameter stainless steel. - 200mm approx flat milled down the inner section of the thumb lock screw - 1/2 inch diameter stainless steel construction - Military grade stainless steel with a unique hardening process - Distinctive Colosseum fluting - Ergonomic thumb screw
