When to choose it
This inside model gives a listed four-by-five-inch blade size. The photo shows a curved transition between its wings. Verify the actual radius and angle if the profile has to match an existing corner. The overall wing size cannot tell you the radius of the bend.
The listing describes a lightweight stainless blade for working compound over a taped corner. Compare the maker's sharper inside trowel when the joint needs a defined fold rather than a rounded working face.

Questions about this product
Does four by five inches tell me the radius?
No. It gives the listed blade size. Check the curve separately if it needs to match the existing joint.
How does it compare with the 23D?
Compare the visible contact profile. This edition gives a radius, while the 23D is documented for a defined right-angle corner.
Can I use it on an outside bullnose?
Choose the correct outside profile for a projecting edge. This variant is intended for an inside corner.
