4 Inch Copper Nails - Pack of 10 Solid Copper Nail Spikes

I ran a test using digital thermometers and the nail did nothing to speed the cook time of the potato. Also this discolors the potato and is potentially toxic so if you decide to replicate this experiment don’t eat the results. Otherwise they are sturdy and shiny and embody the essence of nail-ness that one would expect.

Bend after one hit with hammer. I guess that is to be expected with thin copper but wasn’t expecting it. They would be great if you can figure out a way to hit them into your selected material without bending.

I was trying to kill these tree bushes that kept growing back. Had to get my son to help hammer these into the stumps because they are so thick I could only drive them halfway in. They do kill the bushes after a few months but you should either pull them back out or saw under them after your done. Best to leave enough room in the stump to saw under the nails later. Any unsuspecting landscaper who saws into the tree or bush could get hurt when their chainsaw locks up on the nails.

Used for flint knapping/pressure flaking

These look great, but it will take months to know if they work. We'll see!

I’m expecting these to work just fine.

Been a while and it didn’t do anything to the stump. Follow every steps from the instructions and even used all the nails in the bag for 5” wide stump. Waste of money.

A little pricey. Copper has a golden color, but it's not Gold!

Good quality and copper nails of this length are hard to find in hardware store, perfect for decks and wooden walkways

One spike killed a very difficult Manitoba maple.
