Pleasure to share this with folks who are equally enthusiastic for the topic and swords. Only reason for sharing.
I wouldn't knock the katana stands over much. They have been a practical and reliable medium for the past 9 years. Constantly reconfigured as the collection grew, with out a hitch. Only real problem I've run into is that you can't really disassemble the damn things after you build them.
Swords are heavy, but my book and recording collections are probably heavier.
Most of my stuff is low end enlisted soldier stock. Not literally treasure. Don't want to give the wrong impression about what's invested here.
Maintenance: Actually refurbishment on receipt of the sword is the largest time cost. I have had occasion to buy some swords that looked like train wrecks and sold cheap, but I had guessed were recoverable. Routine maintenance is pretty simple. Mostly it's just oiling and waxing. Couple of racks a week, twice a year. It is fun. History in hand.
Replicas have an important place in all of this. The good one recreate an unreachable past. The stinkers teach you the qualitative difference with the antique, allowing you to be conversant in the history and informed of what might get passed as a fake on the market.
Will take some time to refine the thread.
Cheers
