Review: Works well - Never used one of these before, now I wonder how I would drywall without it. Removes chipping and flattens the edges quickly with little effort. Made very well, an excellent value for the money.
Review: Very Handy Surform For 99.9% of Uses - This thing is only five and seven eighths inches long but it made fast work beveling the edges of several calf blocks I made (used for exercise training). Each calf block is about two feet long. Rounding the edges took about ten minutes, working carefully. It did a nice job. Sharp and clean. The wood-paper-like residue just fills up inside. Not a problem at all as it can be very easily plucked out when full, or it will just push out on its own when full. You can also install the easily removable blade so that the teeth face in either direction, so you can push or pull. But you can do that just by turning the entire unit around too. the blade has simple, symmetrical turned up edges built on to either end that hook onto the front (lower end as per the picture) as well as onto the removable screw "other side of the hook" on the back end. Very easy and very stable design. I like simple and strong tools, since they last and are easy to replace parts such as blades on. Delivered on time; I'm a prime member so two days. I also like that it has replaceable grater blades. I assume that since they are Stanley that the 21-398 replacement blades are easy to get. This efficient little surform was comfortable to use for me, having size extra large hands. I would recommend the Stanley 21-399 Pocket Plane (even though it is really a surform) to anyone for anything but truly big jobs. But I can't think of an instance when you would need a longer grater on a hand surform to shape wood. I have only used it on relatively new wood so far, not plastic or metal. And it cut, shaved and shaped like butter. I am not sure how the blade (or any surform blade of this type) would work on metal surfaces, or on the 300-year old wood of the house I grew up in in Lattingtown!

### ⭐⭐⭐⭐⭐ An Essential Tool for Precise, Aggressive Shaping.
*by B***T on October 30, 2025*

This is the ideal tool for dressing the edges of cut drywall sheets. Unlike a standard rasp or sanding block, the perforated Surform blade shears through the gypsum core and paper facing without clogging or causing the paper to tear. The rigidity of the die-cast body allows for precise control, making it incredibly effective for creating clean, uniform chamfers on butt joints.
