Are those wire looking things actually wires? If so, they might be magnetic. If they are it might be easier to get a big magnet and just hover it over a small ammount of the sand and get them out that way.

If they are something other than metal or not magnetic you might get away with using a strainer or something, but I don't have any experience with this material and don't know if a properly sized strainer is available.

Just my two cents.

It's almost a glass like material. It is extruded in strands and then ground up and sifted through shaker tables. Some of those wire like pieces just didn't get ground up enough and make it through the screens.
I've got a ramshorn snail and ottos with no issues. I've seen them go right over the points. I thought they were going to get stuck, but they were fine.

I just bought a few bags today and I also have the needle like pieces. Not too bad to handle though.

Do you think this substrate would affect whisker shrimps?

While those pieces may seem tiny and sharp to us, to small fish and shrimp they are like a 2x4 or a fence post to them and unlikely to ever hurt them. Those pices are just related to the batch and the quality of the material.
