Our History

The CobraHead® Weeder and Cultivator was developed by modifying a blade design from an extremely popular antique garden tool. The original tool was a long handled five-tined cultivator. Many thousands of these tools were manufactured in the first half of the 20th century. There were many models made by quite a few manufacturers. The level of quality varied. The best tools featured well made replaceable blades forged of high quality steel.

I still use these old cultivators instead of a power rototiller because they are superior for the raised bed type of gardening I do. They involve labor, but they are efficient and the good ones last forever. They are also superior in ground cutting action to any of the tined cultivators being marketed today. I assume that the market collapsed for these excellent tools because of the acceptance of the powered rototiller after World War II and the fact that the tool requires the use of significant manual labor.

The initial idea for the CobraHead® Weeder and Cultivator came to be when I was working with the old tool and a tine loosened and fell off. Scratching the dirt with the single tine, I decided that the digging and cutting ability of the blade might make it a handy weeder. I mounted the blade into a short handle sized piece of wood and began grubbing around in the garden. It became readily apparent that the tool worked very well as a weeder and also did a reasonably good job of cultivating and digging small plants for transplanting.

I improved the usefulness by inserting the blade into a wooden replacement hammer handle. This made the tool much more comfortable and efficient. After using the tool for a season, I decided that it had market potential. I had to find out two things before deciding to try to market it. First, was it really as good as I thought it was? Second, was someone else already making it or something really close and was it protected by a patent?

To prove it was the best, I bought all the similar tools I could find and compared them to mine. After trying most of the best selling hand held weeders I was convinced that the antique blade design, which could be compared to the tine of a tractor cultivator, cuts ground so effortlessly compared to all other tools that it could easily outperform the tools on the market known as the best weeders. It would require modification to the blade to make it more useful as a small hand tool, but I was certain it would be an exceptional device.

In contacting a patent attorney, I was introduced to a program for inventors run by the University of Wisconsin - Whitewater. Their program included running a patent search and a marketing study, and as a result it was determined that the exact product was not currently being made. No patents appeared to exist for the tool, and the market seemed large enough to support another garden tool, if it were unique, so the business was launched in the year 2000.

I have always been an organic gardener and committed to the sustainable approach to life so I made it his mission to have the tool made locally instead of overseas. The Midwestern U.S. used to have a huge tool industry, so I assumed there was bound to be some remnants of that left in Wisconsin. This actually proved to be an incorrect assumption as only two Wisconsin firms were found who could produce the small forging required for the tool. One, the largest manufacturer of lawnmower blades in the US, blew us off after the initial inquiry, so the ability to get the tool "made in Wisconsin" went down to one firm.

A Green Bay, Wisconsin firm, Green Bay Drop Forge, specializing in small forgings for the automotive industry, was capable of making the blade. They showed exceptional and friendly encouragement in helping us get the tool designed and made. They developed prototype-manufacturing prints and established tooling and manufacturing costs for both prototype and full production runs. An order for tooling and a 1,000 piece sample run was given to Green Bay Drop Forge on July 20, 2001.

The pre-production prototype models of the tool used a wood replacement hammer handle. The original production handle was injection molded plastic in the same hammer handle shape. The plastic handle was stronger and cheaper than wood. While the first tools used a virgin plastic strengthened with agricultural filler (flax shive) for strength, the tool handle is now extremely environmentally friendly, with the plastic content 100% post-industrial recycled polypropylene and the strengthening fibers either 100% post-consumer recycled wood fiber or flax fiber.

An injection molding firm produces this handle. The handle making process includes mounting the blade in the handle as part of the operation so the manufacturing process is complete at the injection molder.

The CobraHead is a unique tool. The same or even a closely similar tool is not being manufactured by others. It is probably the most versatile and useful small weeding and cultivating device on the market. It has been enthusiastically endorsed by the best garden writers and horticulturists in the US, Canada, and the UK.

Think of the CobraHead® blade as a "steel fingernail®" and its functionality becomes readily apparent. It's a great weeder for all types of weeds. We've actually had gardeners tell us that it makes weeding fun. But it's not only a great weeder. It digs and cultivates and does a lot of chores that used to require multiple tools.

We have tagged CobraHead® - the best tool in earth®. Gardeners who use the tool know we aren't just throwing out marketing fluff with that statement. There is not a better small weeder out there.

CobraHead Long-Handle

We began developing a long-handled CobraHead soon after we introduced our originalCobraHead Weeder and Cultivator. It quite honestly was a reaction to older gardeners who at trade shows kept telling us, "that looks great, but I need it on a long handle." When we got serious about making a long tool, we realized that just sticking the CobraHead blade on a hoe handle was not going to produce a very effective tool. We tested many blade shape configurations before we determined that positioning the blade so it was perpendicular to the handle gave us a totally new tool that was a useful device for gardeners of all ages and a vast improvement over similar narrow bladed tools that were previously marketed.

We also had to do a lot of work on developing an effective handle. The recycled plastic composite we use for the short tool cannot be used in a long configuration. We settled on a very traditional wood hoe handle. We also had to develop a locking collar that allows the user to replace the blade should it break. The collar gives the tool enough heft to make it effective in tough soils. It doesn't just bounce off hard clay, but cuts into it. Bowman Handles in Batesville, Arkansas manufacture the wooden handle for us using North Carolina Ashe.

Older gardeners and those who have trouble getting down on their hands and knees are quite happy with what we came up with, but we find we now have a market for the tool with small scale farmers, landscapers and of course both the vegetable growers and ornamental gardeners that make up most of our customer base.
