Review on 50-Pack - USA Made - 8-Inch Plastic Edging Nails, Spiral Nylon Landscape Stake/Anchoring Spikes for Paver Edging, Weed Barrier, Artificial Turf, and More (Fits Most Brands: Dimex, EasyFlex, Proflex) by Jermaine Krishnamoorthy

I used these without the digging vigoro edge and they worked fine. The landscape edgings only came with a few and I need more but a pack of 8 was about $10 at the store and it was a better deal as I plan on making more edgings. A rubber mallet is preferred, but I used a 2-12 pound rotary hammer and gently hammered them in. If it didn't work out, I didn't force it and just moved on to the next hole, which worked great. If I need more I will buy it again.
