Thought i try to see how long i can catch with the same hook over the last 48 hrs. Size 14 Animal hook to nylon that costs 16p. I kept the same hook but refreshed the hook length a few times. 2 x Rivers mixed bottoms, 1 x Stillwater with a silty bottom. 32 fish with a mix of Rudd, Tench and Carp on Stillwater. Hook still sharp. Still caught me out a few times by hooking myself. Ist River. Sandy to stone bottom. 18 fish Carp, Trout a few Roach. Due to the stoney bottom and weed, the hook had started to lose its edge. 2nd River Stoney and weedy again. 20 fish mix of Rudd, Roach and Bream. So one hook gave me a sack of 70 fish. At the end of the sessions, the hook was pretty dull and more noticeable due to losing more fish. I put this mainly down to the stoney bottom or the Rivers. I would normally change a hook once or twice per session or when needed. So i suppose 16p ain't bad to last me that long.
