Warner Manufacturing Tool 214 Adjustable Inside Corner Trowel

Just what I needed for some oddball angles. Easy to take apart and clean. Easy to adjust. Some have said it is too small but it is the same size as my fixed 90 degree angle trowel.

When you need it, its worth its weight in gold, but for basic 90s it doesnt work as good as a 1 piece corner trowel.It doesnt stay true so it requires 2 hands to hold fins out but it will get er done on wierd angles.Or, just mud and sand untill they round.

This tool has two main flaws which I will address. I am a handyman and don't do large sheetrock jobs very often. So, I thought this would help me finish some odd angles on a vaulted ceiling I was installing. I was able to make it work, but it didn't really save me any time. I still had to go over the joints with a larger finishing knife. This is due to the flaws in the tool. Additionally, it takes a lot of hand strength to tighten the wing nut enough so that the tool stays locked at the angle you set. Now for the main flaws.First, the tool is not wide enough. The blades should be at least an inch wider, maybe even two inches wider. The mud pushes out past the edges of the tool leaving a ridge which has to be addressed. Wider blades would help fix this issue.Second, there isn't enough flex in the blades. This makes it difficult to keep the point pushed sufficiently into the corner to make a straight line and push the mud evenly tapered to the edges of the blades. This appears to be due to the manufacturing process. The blades are identical. One is turned over so they can interlock. If they were made as a left and right, the mounts could be placed closer to the bottom giving more flex at the top.I was able to make it work "good enough", but it didn't save me any time. I can't imagine that someone with only a little experience could make it work at all. I am giving it a generous 3 stars since I was able to make it work, but I would not buy this tool again.

Beautiful tool!!! Made the job of doing corners soooo much easier for a novice. Quality is also excellent.

Useless Tool. Can’t do sharp angles. For any other you can use standard tool

Product worked well on our 45 degree drywall joints which require a 135 degree trowel.

I bought this inside corner trowel to finish some non-standard corners in a drywall job I was recently working on. I've been doing all of the work myself, including drywall finishing and although I'm a decent finisher, finishing inside corners that were not 90 degrees was a challenge. This did a great job of making the corners look good. I only gave it 4 stars because it doesn't seem as sturdy as my other "professional grade" tools and may not hold up to professional, every-day use. Other than that it's a great little tool for the price and should save the DIY'ers some aggravation.

Finally thought I'd be able to make perfect joints of odd angles with this cleverly-designed tool, but I had no such luck. First, it was very difficult finding the right angle to adjust the tool to...perhaps including some written instructions with hints could have helped. Second and worse, the sides are only 3" wide, just barely wide enough to cover the bevel (1" less wide on each side than my 90 degree fixed corner tool--see pic with angled tool at top). Maybe this was why I had so much trouble holding this tool at the right tilt so it didn't put a big groove in the joint edge or plaster too much joint compound on the sides instead of giving it a feathered edge. Ultimately I had to freehand my 110 degree joint separately on both sides to finish the job.
