I bought it for trial on the 10th discount day. The difference from the flat head screwdriver is that there is a simple mechanism that pulls out the needle by pinching the needle to be pulled out so as not to escape the needle. It is easier than drivers to get out if you can get in under. Tucker needle in the middle of the board is also different from the driver "Loko" works but I thought that even the nail pulling was enough. Since it has a rounded tip, it is very hard to slide in and soak in. The flat head screwdriver is easier to snap in because the tip is hard and there are corners on both sides. After all, I made it with a tool with a flathead screwdriver and I pull it out with this tool. I think that I will cut the shape of the tip to the sharpness of my choice. However, the table is hard to scrape due to the mechanism of pinching. I think I will cut the back uniformly.
