Excellent choice, my friend.
I can see we're going to have fun here!
That one's very interesting. Is that steel blade attached to the cast handle in a fixed position, or does it pivot?
Thanks Cambertree, but I seemed to have jumped the gun a little in posting this before finishing with your two intriguing examples.
There have been some good suggestions offered on this bladed tool (which does have a fixed steel blade by the way) but nothing correct yet.
Sorry for coming out a bit to soon and I hope everyone can focus on a solution for your mystery blades first.
I'm also in the camp that believes hot water or steam was injected through those tubes in the handle of the second knife to warm the blade???
