It’s not a samurai sword, but we think The Bride would enjoy this higonokami knife anyway, with its hand-forged blade, brass handle, protruding tang and lack of locking mechanism. Available in pocket and mini versions for your convenience.
Turns out that SamRenMu, Ganzo, Navy, Enlan and a few other companies make complete knock-offs of the most popular knives made by Benchmade, Spyderco, Kershaw, etc. These can usually be had for under $20 shipped. Only major drawback appears to be the steel is slightly down market (440c or 8cr13Mov) but it's not bad. Worth a look if you're on a budget and want something reasonable.
