Ordered new blades.

Went to the junkyard this morning and cut a windshield out. I think I left my 1", 1.50", and 1.75" on top of the car I cutout.
>Went to go cutout my windshield
>Can't find my blades
>Ask mate that was with me and he told me he set them on the car after he put the small blade back in
I remember him grabbing them when I grabbed the windshield. I have no idea why he would've set the blades down.
>He grabbed the cold knife

I went back to the junkyard and the blades weren't there.
>Hood was now propped open
