Nokia chargers are smps based, i think you should use a auto bulb in series for safety otherwise it will blow your charger.....this applies on transformers base cutter too......

yes it will blow up , there may be chances , i have had an experience ,

ok there should also be any other similar good way of building foam cutter , any idea ?

i use a simple one...

wooden  bow ( just like the real  bow) using heating element   from  induction cookers( get  some from repair shop or spareshop) a 12V 3A step  down connected directly.... works  good

the  tension in the bow will help it stretch,, and not sag
