@MarineBob Yeah. I used to go on different routes walking every day through neighborhoods and would pick up all the sharp metal that I found and collect it in a big jar during decent weather. They are also used by some roofers to clean the yard around the house. So many nails pop off the shingles when they are removing them is why. I asked the last time we got the roof redone if I could borrow theirs and I went all over the yard and found quite a bit of screws and nails that way. Some of them might have ended up as shrapnel if the grass catcher was off of the mower.
