not ok for professionals.

I am a drywall who hangs six day a week and was looking for something like this. when I saw 5/8 on there I thought great. so I got one. (to the person/s who made this product.) You should have tested it first because unless you weight 200lbs or more you can not hold a 4x12 sheet of drywall 1/2 let alone 5/8.^M
my rating on this product is don't waste your time.^M

Almost but not quite....

I bought this tool for it's seemingly small size, it would pocket easily.^M

The issue is that this tool is too short to be an effective lever. Notice in the photo, the radius opposite the lifting end. It's too sharp to be an effective lifting agent. When it does, it usually rips the edge out of the drywall, because the weight of the drywall is sitting on a very small lip. Not that broken drywall can't be fixed...but what a time sink. The rasp is as reported...in effective. A hand held surform (Stanley 21-399 Surform Pocket Plane) outperforms...hands down in every instance.^M

On the flip side, the tool has a small lifting ledge, that works as a scraper or small prybar on solid objects that are not prone to breakage. The mass of the Pocket Kicker works well if you don't want to mar a surface when hitting with a hammer.^M

This tool is not well designed when lifting a 4x8(+) sheet of drywall.

Perfect for the homeowner for patching drywall.

I purchased this pocket kicker for a small, upstairs, rough framed storage room I was finishing as a weekend project. I figured,"hey, kill two birds with one stone." As it turns out, this tool is not suited for the job of drywalling even a small room. As a previous reviewer stated, the rasp edge does not take material off aggressively. To fit pieces snugly, drywallers often cut some sheets for such a tight fit that an edge rasp is needed to get a good fit. The pocket kicker is not suited to this task. You will tire your arms out in no time if you attempt such. As a kicker, this tool is horrible, it is to narrow to be effective. Sheetrock tears on the bottom (not a huge deal, but annoying) and it is difficult to keep the kicker in place while fastening the sheets. Not a bad tool to have in the home tool kit for repairing and patching, but not suited to hanging an entire room.
