Huh, I never thought of how the oil might smell. And I use my oven, too. I guess I dodged a bullet I didn't even know was coming.
My most recent was a recreation of a Tlingit war knife with double ends. Not one of the ones with a carved hilt or totem on the end, I consider those religious, so I don't try to copy them.
Anyways, it was pretty basic with a median ridge and a concave belly with a wooden handle wrapped in cord. I have to get some leather strips, apparently, before fighting, a warrior would use the straps to tie the knife to his hand.
It's not sharp, I plan to use it in classes and demonstrations about the Native Americans and that they did use metal prior to European contact.
