why not just sharpen the blade when it get dull??! so that box cutter is a slipjoint and not a locking blade? personally I would hate to have the cutting edge so far from the finger, even the 10-20mm that is common in many knives drives me insane. personal preference thou as a lot of people seem to like knives that have it. also there CAN be a legal issue as you can take out the blade and use it as a fixed blade, or hold the knife around the blade case. I know it sounds stupid, and it is, but that's how it goes with knives sadly. Before people start protesting again, this is what happens: you get random stop searched. the police will not accept that the knife you carry is legal. the knife is confiscated and you will be prosecuted. the prosecutor will bend any law and do anything in his power to try to convict you. don't believe me? look at the law and see if you can find an actual law saying you're not allowed to carry a locking blade... there is non. a man got prosecuted for wearing a folding knife, in any other country, they would not even have a case against him. the law only bans fixed blades. the prosecutor however manages to convince the jury that once the blade is open the lock transfers the knife into a fixed blade. does it make sense? no. do we still have to abide by it? yes. oh and I understand Finius found a knife thou I do not say that this should stop the discussion as members might stumble across the thread in the future.
