Hi all, 

  
Found a great score yesterday at an op shop that was closing down - 6 stainless steel Sheffield knives for $3! 

  
They're very popular in New Zealand; everyone's grandma has one that they use for everything and promise to pass down to their favourite grandchild lol. 

However, they're unlike any others I've seen. They're not as rounded, and they've this serrated edge on the blunt/top edge of the blade. 

They're clearly not bone, I imagine they're either mother of pearl shell or resin, as they've been damaged by what I assume is a dishwasher and one handle has already snapped. I'm not bothered, I'll find some blank handles and replace them, they're worth looking after. 

I have looked all over and can't find anything similar online, none have the shape or serration like these. I don't think they're knockoffs, as they're just as good as the heirloom one my grandma has. Used one last night to cut very ripe squishy tomatoes, and cut up some apples for the kids today, and they cut like a dream, like no other butter knife I've used. 

Honestly any info at all would be amazing, especially what the serrated edge is for. Google is letting me down and I'm so curious! The only thing I can think of is maybe it's for peeling fruit & veggies. 

Found these antique Sheffield knives in an opshop in New Zealand; they work just like the ones I've used before, but look different to anything I can find online. Any info welcome!
