An Essential Tool for Precise, Aggressive Shaping.

BrettOctober 30, 2025✓ Verified purchase

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. Read more

A Basic Tool for Basic Jobs

Patchy FogFebruary 15, 2013✓ Verified purchase

Well, I needed a planer to trim a pantry door which was scraping on recently installed laminate flooring. I saw that most of the "newfangled" products cost a small fortune -- I was not up for that. I remembered from my youthful days working summers with my HS maintenance crew and my days as a stagehand that we used to use smaller handheld planers on doors and scenery. So I looked around on Amazon for something small and inexpensive. Once again Amazon came through for me! I shaved our pantry door in minutes and now our universe is almost back in order. I will now try the same on our front door! The item comes with ONE blade, which is held in place by latching it on to one end and then inserting it into a plastic holder at the other end and twisting the knob. Now the blade stayed in place during my work but only after i learned to stay clear of the holder at the one end. There are no knobs to grip on the top part of the unit itself -- you must hold it in your hand as you work. All in all you can't beat the price, and it is a Stanley. I don't know how long the blade will last before it must be replaced. Nor do I know as I write this where I can get a replacement. But I kept my expectations low when I bought it because, after all, you get what you pay for. I am satisfied because I should be able to complete my remaining job, and then I will give it a nice resting place in my toolbox! A basic tool for basic jobs! Read more

Gets the job done.

Alex MNovember 10, 2025✓ Verified purchase

I needed to take a little bit off the side of a door. I didn't want to take the door off it's hinges but a normal plane wouldn't be able to get into the corner. This plane did just that - the cutting surface goes right out to the edge. Did the job. Read more

Very Handy Surform For 99.9% of Uses

VirgilJuly 22, 2013✓ Verified purchase

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! Read more
