Review: Shapes wood like nothing you've ever used before - Shapes wood like nothing you've ever used before! (If you've never used a tool such as this) It moves material crazy fast and the holes let you see what you're doing as you're doing it. I've used a similar product, without the holes, and it worked great. But when I got this one and could see what I was doing as I was doing it, I was thoroughly happy. These types of tools can be quite dangerous, but being able to see your work further reduces the possibility of an accident. If you want to move wood fast and accurate, this is the tool for you. It will need some finish work, but the time saving is well worth what work is left after using this Holey Galahad! Bottom line: great tool for the money. Worked exactly as claimed. Tooth wear has been minimal which leads me to believe it will last for quite some time. I'd definitely buy another if this one ever wears out... unfortunately for the maker I'm not sure it ever will! Great product, fair price, and shipping was as expected (7-10 days.)
Review: Works great! - This only took 10 minutes. Pretty cool tool. I think they are highly priced compared to other grinder accessories which is the only 4 star portion. Knocks out wood very easy and smoothly. First little tester went like butter. Wouldn't lay it flat and would recommend using it at an angle softly to prevent the heavy pull on whatever surface you are working on.

### ⭐⭐⭐⭐⭐ Does what it says, works well
*by W***E on January 24, 2024*

I'm a rookie woodcarver and bought this to use on a maple slab. It fit my Ryobi angle grinder securely and removed wood quickly without "grabbing." It throws a LOT of coarse sawdust farther than you'd think. This was a good investment that works better than other cheaper knock-offs.
