I got the Musashi Katana by Paul Chen and I'm having trouble taking off the handle. I took the pins out with the little hammer and held the sword with my left hand and beat the hell out of my left forarm with my right fist but to no avail. So next I tried the wooden mallet on the back of the blade and struck it quite hard but still no luck. Whats next? Wrap the blade in cloth and put it in a vise then pull on the handle? Has anyone had this problem, please let me know.
