The Katana boys get worked up about the slightest detail of construction,steel types, layering, patternings heat treatment boundary forms, and have a billion terms for them, before they even get to the mounts and grips. Bit like the Keris people here
Is a european yataghan bayonet a yataghan? or not, just because it was capable of being mounted on a rifle tends to put purist's knickers in a twist. How about a Yat bayonet turned back into a sword? (I bought a really cheap 1866 french yat bayonet, the Horn handled hunting sword yat fits it's scabbard perfectly.
I now have a yat bayonet spare...scabbards are harder to find than the bayonets...
