The Goods Japan ones look very similar to the Barry King and Osborne creasers.  They will work with an alcohol lamp.  Wuta irons are pretty popular.  Google reviews.  I use an electric one.  When I was a kid my father gave me a screwdriver and told me to put it in that hole in the wall.  Well, it was shocking.  I learned about electricity and have no fear of it..  Take that one you have and light that sucker up.  That would be proof positive. https://www.barrykingtools.com/handtools.ht
