That’s a good question… I had a knife “incident” this morning with my packed lunch!
I shouldn’t jest on such serious subject matter but it’s a surprising stat and I’m not sure I believe it tbh.

Looks to be from Table p5.
I can't recall where I saw the initial table but there's an interactive graphic on this link:
Worst areas hit by violent scourge of UK knife crime – MAPPED
A total of 282 homicides in the year ending March 2022 were committed using a knife - the highest annual total on record.

Possibly out of date information now, but like I said, it's not a great pissing contest.
