Thread: Any info on this blade AND What would you call this tip?

So here's a blade that made it into my keepers (in the process knocking out my W&B Bow). She's shoulderless, quite wedgie, and stamped Best Silver Steel K*R.

I'm guessing she's a Sheffield blade, but I was wondering if anyone knew anything about her origins for sure.

I'm also wondering what one would call the style of the point. The cutting edge extends past the spine, and there is a curve almost like on a Spanish or barber's notch. (If it's not clear enough in the picture I have, I can attach another).
