Single-edged blades with a ridge

bookandswordblog · 19th March 2026, 12:33 AM

It seems like T-sections were popular from the Ottoman Empire to India in the 18th and 19th century? I wonder how they made them because that shape can be a pain to grind and polish.

Blades with a ridge a bit forward of the spine remind me of a classic five-sided katana blade. I don't understand blade engineering well enough to understand why katanas have that section. Guillaume Stanislaus Marey-Monge thought it made for good cutters.
