Hi JPN, Yes gotta keep it sharp or as you know you can injure yourself if the blade is blunt. Unlawfull use of knives is common in some parts here, almost every day ie stabbings although not where I live fortunately. You have to have 'lawfull authority' and 'reasonable excuse' it can't be a lcokback and the blade has to be no longer than 31/4". I can carry a straight knife to and from a stalking trip but if I called into a bar on the way home with that type of knife on my belt, I'd be in trouble. There have been some high profile murders here ie of a scholl head teacher which does not do anything to help knife collectors. When I lived in Scotland as a lad I always had two knives, a pen knife and a straight knife.
