What gift would you recommend for a man fisherman?

I know that every fisherman buys and uses special equipment that seems to him the best and, most importantly, the luckiest, so I wouldn't recommend that you buy new spinning rod or bait. I know that you can find many interesting fishing accessories on the Internet, such as a folding chair or flasks for men would also be a good gift for your father if he loves night or winter fishing. Search the internet for many other but simular offers.
