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.

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.

No more broken nails or busted knuckles trying to pull weeds and grass out of concrete cracks. I wish the end was a little thinner or sharper so you didn’t have to use as many strokes to cut through the weeds growing in the sidewalk cracks and if the end was a little thinner it would make it in deeper sidewalk cracks and I would be able to just scoop out any leftover debris that might fall back into the crack instead of still digging my fingertips in them. Unless, I’m not doing it exactly right because all the instructions written on the package are in Chinese. If anyone wants to reply with English instructions it would be appreciated. Overall, it’s a good and simple product that does exactly what it describes on the site. It’s also well constructed and seems strong enough to handle rough garden work. It’s definitely not a flimsy piece of junk that will break day 1 of working in the garden.

Grass always starts to grow over the edge of my driveway - this is perfect to chop it off and make the area look nicer.

I’ve bought many garden weeding tools but this one is different. It’s so effective at removing grass and other “creeping” stuff that grows in between the cracks of my pavers on my patio. I highly recommend 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 the perfect tool for removing weeds in cracks. I never have much luck using my trimmer as I always have to refeed the line. This? gets deeper into the crack and you can quickly treat it with weed killer.
