TAJIMA's wood, aluminum, and plastic grinding tool. The file is medium grit, equivalent to #220 to #280 sandpaper. According to the manufacturer's advertisement, it grinds more than 6 times faster than sandpaper and lasts about 100 times longer. I have used it several times for DIY projects after purchase. The file surface (photos 6, 7, 8) still seems usable (in my personal opinion). The size of the file is shown in photo 9. The grip makes filing work very easy, and I think it's a good tool. By replacing the file, it can also be used for coarse and fine grits (photo 10). There are minor scratches on the handle (photo 11) from several uses, but no noticeable scratches or dirt. This is also my personal feeling. ✳︎The handle will be disinfected with alcohol before shipping✳︎ Model number: SA-50C Product weight (g): 95 Price including tax (yen): 2,310 Price excluding tax (yen): 2,100 JAN: 4975364050427 Sander SA50 Medium Grit Wood, aluminum, and plastic grinding tool Excellent workability and durability Grinds more than 6 times faster than sandpaper and lasts about 100 times longer Can grind in any direction relative to the grinding surface The blade is easily replaceable
