Abstract: A fishing knife has a handle defining a blade slot and a blade pivotally mounted between open and closed positions on a pivot pin extending through the handle. The blade has a tip, a sharp edge and back. A line cutter including a recess is defined in the blade back and a line cutting edge extends across the recess. The recess is disposed away from the tip of the blade. The line cutter is a replaceable cutter insert received in a matingly configured slot defined by the blade. The handle defines a recess cooperatively that exposes the line cutting edge when the blade is closed. The blade defines an arcuate pivot slot having enlarged lock openings at each end. A spring biased blade lock plunger extends through the pivot slot, and has a lock portion that fits in the lock openings to secure the blade in closed and open positions. The plunger is axially shiftable to position a release portion in the pivot slot, permitting the blade to pivot.

Abstract: A modular fly fishing reel includes a frame with a side wall, a generally cylindrical axle cartridge removably mounted in a mounting socket of the frame side wall and also having an outer rotatable axle tube, and a spool having a hub removably secured on the axle tube by a quick release mechanism. The axle cartridge includes a drag assembly adjustable by a drag nut positioned adjacent the frame side wall and acting on the rotatable axle tube and spool. The quick release mechanism includes a detent that is spring biased through the spool hub to engage the axle tube, and releasable by a slide button or push button mounted on a spoke of the spool. The spool has a rim defining a line pocket and the side walls and bottom wall of the line pocket are convex for high strength and low weight.
