Marshalltown Exact Angle Inside Corner Trowel, Drywall and Plastering Corner Trowel, 90 Degrees to 154 Degrees, Easy to Clean Nylon Blade, DuraSoft Handle, EA917

The complaints that I saw were that it is too flexible. That is a good thing and this tool works great!

This drywall mud spatula is adjustable and worked really well on a lot of different corner angles.

It will kinda work in a pinch for an obtuse angle. If you need a 90degree corner trowel just get a stainless one.

Thus far, this is the best solution I've found for varying angles. Most pros will just use a flat knife, but using an angled trowel gives you the advantage of a nice, clean line. Also, using a straight knife doesn't force the compound into the corner as tightly, creating a much greater risk for pockets, which will dramatically weaken your joint. The only problem with this trowel is that it is plastic and flexible. When you tighten up the angle, it forces the plane to skew slightly, and round the leading edge, leaving you with somewhat of a rounded corner. I have a 1907 1-3/4 story house, so I have 45's EVERYWHERE, and being that it's an old house, none of the angles are uniform. That's why this makes a nice addition to my toolbox.

It's just ABS plastic. It arrived warped in the box. I suspect that even without warping it still wouldn't have been veryy functional. Fresh out of the box it was pulling jagged lines with divots and gouges. I tried running it wet, still the same thing. It holds mud, doesn't glide along even relatively thin mixes. Overall quality was surprisingly awful, despite being a Marshalltown product, I like their standard mudding knives, especially for a somewhat budget option. Do not expect Level 5 quality, but if it's something you are trying to use once to pull a weird angle, it's ok, just expect a lot of sanding and sculpting.

This is an outstanding product. At first, I was disappointed with it being made out of plastic, however, as I got to using it, I realize that any other construction would have been counterproductive metal and hinges would have created more problems For the money, it is well worth it.

Great tool, of course I am very good at topping, not to sure how it would work for someone with out experience, just have to have patience.

Bought this because I have some strange angles on my ceiling and hoped it would work since it's adjustable. One it came in 2 pieces, missing the wingnut and washer so had to find one to fit it.The sides are a soft bendable plastic so they really don't work at all, they just bend if you put any pressure on them at all while holding the handle. It kind of works if you put your fingers behind the plastic to give it extra support but that's really awkward and hard to make a nice smooth crisp corner.
