Can anyone help with Identifying this knife....

hi everyone here on AAPK. I just wondered if anyone had seen this model of what looks like a prototype of the so called Christmas Knife? I have taken a photo of the knife at the side of so called gift knife but I believe this to be earlier. The handle is all copper with a copper bale. I cannot make out the makers mark but can just make out - Sheffield. I would appreciate any information and if anyone has seen one before.
Also I have put a photo on of some knives I have for sale on my ETSY shop.

I have never heard of "the Christmas knife". Maybe it is a U.K. term ?

the knife at the top is known as a Christmas knife as they were given to troops in ww1 at Christmas. also known as gift knives.

I have seen the very top knife style listed on Fleabay but under a different name if that is any help...?/?
It was fairly recent, like within two months.
