These are some photos of my latest homemade tool. I give to you the world’s first grass whip that uses disposable utility knife blades. It uses two of the long snap off variety. It is made from an off the shelf stairway baluster, rock hard Sugar Maple, Burr Oak, Walnut, some brass stock and of course the snap off utility blades, two of them.

Some folks call it a sling blade, I call it a Kaiser blade.

(and I know it isn’t a Kaiser blade but that’s a great movie)

Pretty cool, would also work with planer blades.

I’ve always called it an idiot stick. Nicely done.

Great innovation,

Watch out, someone will steal it if you aren’t cautious.

Good Luck!

Thanks for the words of support and caution. I know I am playing fast and loose, but, the way I see it, I need to get the idea out there. I have also applied for a provisional patent from the USPTO. Plus, if some one does knock it off, that demonstrates desirability. And, having an idea with my name attached to it out there, even surrounded by litigation will serve me better than an idea that is just rolling around in my head. I have been down the inventors path a few times and have come close to that big deal once. With the likes of Quirky and other crowd funded innovations, the landscape has changed considerably. I suppose the worst thing that can happen is nothing. In the meantime I am soldering on with garage manufacturing utilizing off the shelf parts and Sugar Maple. I have at least 30 – 40 other ideas that are just as saleable and of utility as this, in my humble opinion. I’m getting on in years and I need to get some of the ideas from my note book out into the market place. Time will tell if my approach is foolish or a good one.

Put a sheath on it and it would go perfectly into my golf bag. No no, I’m in the fairway. See the grass is the same height…

It’s a nice looking tool, but what do you do with it? My grass never grows to the height that I would need to use the “grass whip” on.

This was never meant to be a replacement for a lawnmower. It is meant to replace the typical grass whip with the fixed blade that usually is used till dull and then spends the rest of the time in the corner because the owner does not know how to sharpen it, or has moved on to a smoky, stinky gas powered weed whacker. This is to be used as a convenient alternative to the old school grass whip. That is, where there may not be any power available, a stand of large weeds that are easily dispatched with an ever sharp tool, or where the user does not want to use a gas powered weed whacker…like me.

I have made another one, but it is ambidextrous. It has blades on both sides. Personally, when I use a grass whip I usually just swing it right handed because I am right handed. I never swung the whip on the return swing (left handed) to knock over more weeds. This, however, is part of the product development cycle. Time will tell if they will sell or if it matters if it is left or right handed or ambidextrous. I would post a picture of the second working prototype, it is in the trunk. But, I broke the key off in the trunk lid cylinder at the position that disables the open feature from inside the cabin…geeze. Once the trunk lid is open, I will post pictures of the next generation of grass whip.

Here is the You Tube link to the grass whip in action. This is the ambidextrous model. If you would like to buy one, or talk about manufacturing it, please let me know.
