get yourself one of these;
i don't know the propper name but iv heard people call them 'jack knives' cost me £2.50 from the local army surplus
ok it was a little grotty when i got it but after a soak in WD40, a good scrub with wire wool and a good sharpen it has been the best pocket knife iv ever owned. not the lightest knife in the world but the steel takes a wicked edge and it is pretty much bomb proof.
it also has a passable can opener and a marlin spike too which come in handy. also because the blade is only 6cm and is non locking it is legal to carry in the UK
would i rate it over an opinel? i used to have a no.10 which was good but the blade was very thin at the tip which worried me. i stupidly used it to split some wood with a batton which buggered the lock
i do like opinels but for me there is no point carrying a folding knife unless you want to keep the law happy. if your going to get done for carring a locking blade you may as well carry a fixed blade.
