I'm working on a project and was thinking about making a tool for ripping up compacted soil. The big hoe wasn't cutting it. What I had in mind was a one tine cultivator. Then I saw this post and there it was. I just bought the two of them from the company for $80 and free shipping. Cheaper than Amazon (I checked).
And they are American made.
We'll see how they work.

Make sure you report back, Carl!!

Well, my two new weeders arrived yesterday in very good condition. Too late in the day to try them out. (I'm apparently at the end of the UPS route.) I'll try them today.

Well, I tried them out. They work OK as weeders. I think it will take some use to figure out how to best use them.

As a cultivator the Cobra head weeder is less than satisfying. It's more like a 1" wide hoe that scrapes the ground.
I was hoping that it would be more curved and pointing back towards the user. It comes down more perpendicular to the ground and doesn't dig in.
It did not break up hard clay without a LOT of work. I went to the spading fork.

Overall, I would give it 2 1/2 to 3 stars. It's well made, but doesn't do anything better than other tools I already have.
