Absolutely call back! What a crap response!
I was walking home from shop once, late 30s, it was dark but only 8.30pm.
A guy drove up in a car, opened the passenger door over the path, reaching the hedge on other side blocking my route.
'jump in darling, I'll take you home darlin'
I lived 300 yards straight ahead, but wasn't telling him
'What's wrong darlin?'
I walked quickly into the road, around his his car and stood with a lady at the bus stop which was 10ft from the blocked pathway.
She asked if I was okay and who was he. I said no idea and not really but do you mind if I stay with you until the bus comes? No.
Bus came far too quickly, I walked the 300 yards to my house, looking everywhere. I even walked straight past my house as didn't want him to know where I lived.
When safe, got in, called police...
Response was ahh, he probably just fancied you...
This was when young women were being abducted in my town.
I just said yeah, I'm in my 30s, I'm clearly not used to this new approach where path is blocked and a stranger is trying to get me in his car.

Anyway I'm so sorry for that rant @G172125 Don't bin the knife. Push on this. They should have at least said bring it to them to dispose of.
Where is the first place knife owner is going to look for their knife? Well first garden, second your bin.
