Alan_B, I'm sure most of us would.
Nam, don't know if this will help:
All blades have a sort of "spirit". (lack of a better word) The "spirit" will either be weak or strong. This strength usually depends on the blade's purpose, design and maker. Usually, fighting blades by good custom makers have the strongest "spirits".
If the "spirit" is weak, there is no problem. Anyone can carry the knife, use it for just about anything, mistreat it, whatever. There will be no casualties, or if there is, it's usually because of some stupidity on the user's part.
If the "spirit" is strong, then the blade should only be owned and used by one person. That person is usually the first user whose blood is tasted by the blade. I'm not sure about other cultures, but the Japanese Samurai always christianed their dai-katanas with their own blood in a special ceremony. These days, we don't do that sort of thing. So a blade with a strong "spirit" is usually free to find its own master. And that means a little bloodletting on an unsuspecting person. In this case, your wife.
So tell her how priviledged she is that the blade has chosen her. No one else should be allowed to use that blade. It is hers for life and can only be passed to blood descendants. Oh and BTW, please warn the descendant receiving the blade to expect a little bloodletting as the blade gets to know its new master.
And in case she's worried about having to sacrifice blood everytime she uses the blade, tell her that fortunately, most blades, after a little bloodletting, tend to settle down and serve their master without any further problems. Just watch out for those blades that seem to keep cutting you everytime you use it. That indicates a strong
and aggressive "spirit". Or a strong knife that has not found its desired master. In this case, there are two options.
1. Blood christianing. Not pleasent, usually messy and does not guarantee that the blade will behave itself. Usually the master has to have a spirit stronger than the blade for this to work.
2. Keep the blade away safely and either pass it on to the next generation when they come of age, or give it away to a passing itinerant swordsman (or in these modern times, sell it or trade it).
There is, of course, option 3, which is to destroy it, but that would be sacrilege.
So, Nam, tell your wife this story and try to convince her. If not, I'll send you my address and a money order, and you can send me both blades.
