They call it a Lambsfoot - But then they call the knife a 'Senator'

I can't say I care much for it either

I think they think it looks 'fancy!

That knife was an attempt to add something '"more high end" to a range of inexpensive working knives, which I think failed, but you can see the thinking (and lack of thereof) behind it. Strangely, two people claim to have come up with both the name and the pattern, the current owner, back when he was on the shop-floor, and a Sheffield dealer, now retired, so it could be that it was originally an SFO. Personally, I think that with a bit more thought, and a small amount of knowledge of cutlery history, they could have come up with something better, but sometimes it's easier to steal ideas than have your own
