A working platform provided with a manual wood planer is provided with a base the two sides of which are both formed with workbenches, a working platform being thereby formed. The workbench is formed with a pedestal and a granite slate is mounted at the top of pedestal. The slate is polished and ground into a working portion at the top, and a combination portion at the bottom, and several securing holes are on the combination portion. A strip-shaped hole opposite to each securing hole is formed. The position of slate may be tuned and the error margin of distance between the thru hole and the securing hole is allowed to avoid the slate, when being secured, from cracking. With the features of high level degree, low friction efficiency, and no internal stress that are provided in the granite, the working platform is featured with perfect processing accuracy and durability.
