OK! Try number three on locating a ferrous needle!

I am pretty sure I got it this time but I am waiting to hear back from the manufacturer.


There are needles used in the meat handling industry called HDN (Highly Detectable Needle). They are used when the animals are raised for meat. The needles are detectable by metal detectors in case a needle breaks off inside of an animal the plant can be shut down to get out the metal before going to market.
They are expensive but super heavy duty. They are available as singles for around 0.65 or 38.00 bucks for 100. I can't imagine wearing one out using it for mycology, these things look tough! Here is a link to one of the sites that sells them for anyone interested.

I heard back from the needle manufacturer. She told me they should work because they are magnetic. They are still stainless steel, it is just the alloy has been formulated to be magnetic.
