does that mean if we do not bring it in public it wont matter?
(like collecting it in private area, homes , etc)
anyway who says petaling street dosent sell katanas
theres lotsa them in central market
but with stupid prices, bad bad quality
if u're a collector u know it
if u still going to collect that kind of quality things means u're still noob
by the way, japan dosent permit thier registered katana to be exported that easily,
unless u have some rank in kendo or kenjutsu and is a sensei
dont be fooled if someone tell u he is selling a katana from japan and is registered
its probally from china

why dont you make you own choji oil ?
i saw some website teaching people to make it
and if u're in malaysia... better import rather searching for it in malaysia
coz katana's in malaysia are all mass produced from china, with low quality stainless steel
they dosent need to be oiled

there was a shop called "little china" in petaling street that sells ok-quality wooden swrod
(i wouldnt call it a wooden katana as it dosent comes with tsuba)
RM9 for one... well no need to surprise as it is mass produced...from china
so i bought one home for swinging around... and to replace any broken bokuto
its surprisingly quite durable ... survived until now ,gone through lots and lots of brutal hits
anyway when i wanna go back and buy one... the shop is moved away

as for those you see in jonker streets and central market, i think they have the same quality as they looks exactly same
anyway they raise the price up to RM27~45 due to there is no one to compete the price
and to cheat newbies that loves these stuff alot but dont know where to get one

sure.
to register, u need a proper reason to own one real katana
and ofcourse, prepare money ==(lots of them)
but why the hell do someone wants to go through this lot of trouble to keep 1 sharp blade?
just blunt it ,save lots of trouble
