Buy a different brand?
I noticed in tests that Korda hooks lost their points very easily, they are so soft. The water you are fishing can even blunt the point, not running it over gravel, the acidity or alkalinity of the water itself, it seems to be silty lakes more I think.
On Nazeing a mate and I used to 'swap' rigs, our tackle boxes were open season, and I grabbed a rig tied with a Korda hook from his rig bin when I had showing fish in my swim, yet failed to hook one. I was sure I had had pickups, I changed back to the Gardner Mugga's I was using at the time and within minutes had a decent fish on the bank.
He had also been blanking, yet when I gave or tied on one of my rigs on his rods he converted the same indications into fish on the bank.
I am against the grain on sharpening hooks, I think if it's not sharp enough out the packet then buy a make that is. I often check and change the rig after each fish, but check the rig every cast anyway. If I think the point is gone I change it. That is what the ball of my thumb is for, checking the hook point!
