Inside Corner Knife, 4"x3.5" - LEVEL5 | Pro-Grade | Metal Hammer End | Drywall Gyprock Plasterboard Sheetrock | 5-310

Not much to say here works well. Whether it will rust or not so far has been yet to see.

My inside corners look amazing. Super easy to use. Well worth the money.

This seemed like a good idea as a homeowner doing a small amount of drywall work. But the knife is so far out of square that there ends up being a very large gap underneath the knife when trying to spread mud evenly into a corner. The knife also has very little flexibility, so if you try to press it deeply into the corner, you may end up damaging the surrounding drywall. With how much pressure is being applied, the corner will be very nicely feathered, but it will be hard to get a sharp corner. This seems to be meant to give you a nice corner in a single day, but I think I'd be better off just using a flat knife and doing all left corners on one day and all the right corners on a second day. You can probably still do it all in a single day if you use fast drying "hot mud" instead of all purpose joint compound anyway.

I'm a DIYer, and I've fixed 4-5 outside corners with this tool that have taken traffic abuse over 20+ years, plus small touch ups around windows that don't have separate trim (just drywall). It can produce a sharp corner when one is generous with joint compound, and then it's a matter of building out the edges once the initial corner application is dry. I read some reviews wondering why this tool wasn't exactly 90 degrees, and that's not been a problem for me. Other internet sources (how-to videos) explain that it's not supposed to be 90 degrees. It's a matter of how the tool is held during the application of joint compound, and using light pressure to form the corner during the application.

*EDIT* 2-10-20 I thought I had previously changed this rating butI hadn't so I am now. When I originally had this issue with the handle and left the initial review they promptly contacted me to make it right! They went so far above and beyond I was amazed to put it lightly, so much so I bought a complete set of their auto taping tools, bazooka, 10" & 12" boxes, handles, extensions, corner boxes, smoothers etc. I knew they would stand behind those tools after this experience with their customer service. So far I've had 0 issues with everything else including the replacement corner knife they sent me. A+++++ Thanks Guys!! *Old review* Well I would rate this much higher as the angle, feel and handle are great except the handle itself fell off as it wasn't secured to the metal portion of the tool and fell off the first time I used it...... Pretty Disappointing that I have to epoxy it on myself as it wasn't done right when it was manufactured.

As ordered. Well built

the right everything . a must have

Bought to do drywall corner work. The one I received was not even on both sides. One side bent more than the other. Doesn't work well. It now sits in the bottom of the tool box. Not a good purchase. Not what I expected from Level5

👍

思っていたより左右同時に出来るので便利。 収納に困る。

The item is good, but you delivered it two weeks late.

I reveived the Angle corner tool but one side of the blade was not ''deburred'' why?

I was expecting better, i had to push so hard to get into the corner that I'll have carpel tunnel in a week. It might work on an inside 45, the knife is flared out so much that it's impossible to use on an inside 90.
