legal until police cari pasal with you...
my friend have those mini key chain swiss army knife drove in backlane that was one way as he didnt know. then kena police stop and say he was drunk and ask for kopi money... bising bising, then 1 sargent came over ask to check car for weapons and drugs.

Ended up went to balai do alcohol test which nothing detected but kena tahan whole sunday cause got sharp weapon. End up pay Rm500 to settle and he walk free after that, or wait till Monday go court. Maybe kena kelentong by sargent for RM500.
