Look at the previous pages for my bro's design.

officially they are illegal to own in Malaysia

Just a personal opinion here. Dont get me wrong I LOVE Benchmade knives as a whole BUT when it comes to Butterfly knives I prefer the "High End" Cold Steel models over the Benchmades. But if they are illegal which they are here in Maine I would NOT even consider carrying one. This luckily is not a factor for me since I am a Registered Bladesmith I can carry any reasonable blade. I can not carry a Machette for instance. I have a lust for Automatics which are illegal for anyone not an active law enforcement member or Armed Serviceman. But They are also Bladesmith exempt, at least here in the USA.

Whoaa there black bear, I'm no expert, just a fella who loves sharp objects, and a few other things .. in fact my love for these edged tools are currently limited to production pieces only, thanks largely to *ahem* economic *ahem*  reasons

Based on my limited understanding, when something is prohibited in the eyes of the Malaysian law, it stays prohibited, whether its tuck away in a drawer in your house, or carried on your person. To my knowledge, just like automatic knives and daggers, butterfly knives and balisongs are a total no-no. if they are discovered by the custom service in a parcel addressed to you, then you'll be called to the custom office to produce your credential (member of the police force, armed service, etc) or to produce the permit to own or/and carry such item.

or normally, they just confiscate the thing, charge you with attempt to possess illegal weapon/prohibited object and make your life a living hell.

To clear the air, let me paste this here (as plagiarized from a post by my good friend and sifu on sharp objects) :-
Please bear in mind that Malaysia is NOT a land of the free and home of the brave, nor have we the rights to bear arms; hence if there is any reason for the authorities to 'inspect' your house and found this in your possession, or within the compound or property occupied by you, then you shall be made liable and so on and so forth.

a further extraction of the Act 357 also listed the following prohibited items:

funny thing is, multitools and swiss army knives (or SAK) are considered tools and is generally considered acceptable.

most normal folding knives/folders are also considered acceptable. in fact my edc for the last 5 years is a strider SBMF, a classic i know and a boker subcom in the wallet.

Strange that I'm allowed to bring in knifes longer than 4" fixed blade after the custom inspection at KLIA.

Buck Strider is a Fantastic EDC Choice!

I carry different knives most of the time but the one I carry most is a Spyderco D'allara. I simply love this carry.
