You need to ask customer service about a Katana designed for cutting through bamboo
While it can be costly, you can get a good Katana from China where they have been making swords for 2600 years.
As old as the Japanese
The big difference is the cost.
A decent Chinese made Katana that you can build to your specifications if you know what you are doing is $200-$300 range.
Customer service is out of Houston, Texas and is very good.
I do NOT work for this company
If you want to pay more, check out Henwei
Cult of Athena is great on prices if they have it in stock.
As far as a true Japanese Katana, the blade alone is about $6000-$8000. On up.
That does not include anything else. And for an heirloom, maybe 250k
The Japanese government strictly regulates their Katanas unlike the Chinese.
Slicing through a 4 inch diameter of bamboo simulates beheading.
Better to work out your frustrations this way.
