I would be suspicious of anyone asking about my knife out of the blue like that ... here its not technically ilegal to carry a knife , but its just amazingly hard to do so legally ... and not just knives as you'd generally think of a knife as being but " any bladed object" can be deemed to be a knife by the constabulary and confiscated , charges laid etc ...
a lawful excuse to carry a knife is to use eat with .. but then it gets technical ... if you are eating , thats fine , if youre going to eat , no need of a knife cos your not eating yet , and have just eaten , well you dont need it any more youre finished .. no longer any excuse ... at least , this is how the cops I have run into regarding the matter see it .. and they are the guys who decide if they are going to book you or not , if they are going to confiscate your knife or not , and if they are going to do any paperwork on the confiscation or just score themselves a free knife ...
the law is stupid , I could go on for ages about it .. but the end result is , if anyone asks me about knives in general , Ill assume they know me or what I do anyway and talk till the cows come home if they want to .. but if they want to talk about what Im carrying ... then thats totally different ..
that being said tho , majority of people I see here who knives with a clip are tradies who buy their knife , mash it into stuff till it loses its edge , mash it a bit more then chuck it and buy another .. no appreciation anyway
