Nisaku NJP2500 Zassou Tawashi Crevice and Sidewalk Crack Weeder, Japanese Stainless Steel 3.25-Inch Blade, 3.25-Inch Wood Handle, Stainless Steel/Wood Handle

I was really skeptical about buying this but it was $5 so I figured why not ? When I got it, I was even more skeptical, it was small and seemed so flimsy. I thought for sure that using it against pavement would snap it in a heart beat. I WAS WRONG ! I have a motorcycle pad made with pavers, so I get the occasional weed growing around the edges. I had let it go most the summer so I figured it would be a good test for this thing. 20 minutes later, the entire pad is completely weed free ! The Crack Weeder (they should work on that name) was amazing. Just hold it at a 45 degree angle and scrape it along the side of the space, crack or wherever the weed is growing and it cuts even stubborn roots in an instant. I made about 50 separate cuts along the pavers and it never took more than one pass to sever the weed. I thought about buying another one but I wouldn't need it, I think this little thing will be working for years. I recommend it without hesitation, full 5 stars !

I’ve tried using trowels and pressure washers, and this thing beats them all. Hands down. I think the corrugation is the key. It makes quick work of severing or dislodging the greenery that insists in growing in my driveway and pool deck cracks/crevices/seams. I’m really impressed with how quick and easy that was. It showed up this afternoon, and I had all my cracks cleared, front and back, in about 10-15 minutes. Some just took a swipe, and some you need to saw at from both angles a couple of times if they’re well established. So glad I finally found something that works with no muss or fuss. Right tool for the job.

Bought this for weeding my zeric rock garden which became inundated with cheat grass. Tool is sharp, does the job well, but with a few caveats. Tool would work best for those with smaller hands. My hands are medium women's hands, and I could use more handle to grip. The second is a concern about how I used it to be most efficient. Holding the grass or weed up to differentiate them from the perennials requires pulling the cutting tool toward the hand. Doable if used carefully.

This tool cuts well and works as designed. It is a bit difficult to hang on to though. At the same time I purchased a tool with an identical blade with an extended green handle which also cuts well and easier to hold and use.

This brand makes the BEST secateurs/hand pruners I’ve ever used, so I wanted to try their other products. This cuts so much better than I even expected. VERY sharp edge, but not dangerous to just slip into your pocket. Made getting weeds out of peoples driveways fun if you can believe that, lol. Simple smooth wooden handle felt nice in the hand, perfect sized. All around great product. Will be buying more for my fellow gardener friends! 10/10 recommend, and will buy again!

I have a large brick patio that I powerwash and clean the joints every Spring. I love the Sidewalk Crack Weeder. I never knew it existed until this year while browsing on Amazon. I ordered this gadget/tool and I am totally impressed. It is compact, provides a good handle to grip, and the weeding is done in no time flat. If I had only one tool I could own, I probably would choose this one. It is made well, does its job and then some, and is reasonably priced. I am a happy camper and actually look forward to weeding/edging with this tool.

In theory, this tool should be helpful and very handy. In practice, it's not. The product video should have been a warning- the user merely cuts the top off weeds and the device is then used to sweep them away. It will do that, but a basic understanding of weed control is that you have to pull out the roots or they just grow back. It turned out that our weeds were easier to pull out by hand without it than working it around and trying to loosen them with this device. Part of the problem is that the blade is corrugated, which may help with sweeping debris up but which made it too hard to sharpen at the factory; there's a very noticeable burr which renders the blade unable to cut effectively. Also, the blade is held into the handle with a rivet, which requires a good bit of work to remove in order to replace it when it gets dull- which is quickly since you're working on concrete or brick. On the bright side, the wooden handle was finished very well and comfortable. That's peripheral to the purpose, though. Overall, it was a waste of money. Fortunately, getting a no-return refund from Amazon for the separate pack of replacement blades was easy, although now I'm stuck with those and the original device.

This is very simple but effective. It easily cuts through the weeds in the cracks. They are so hard to pull out, basically impossible and I don’t want to use poisons. This tool makes it very easy. It’s a great deal.
