Although I used Saform from before, Tajima tool purchased this item because the price of the replacement blade is cheaper. The use comfort of shaving is the same as the form, so it is profitable as the price is cheap. The advantage of anything is that the blade of this Tajima tool is rustproofing working. Even if the blade washing with water repeatedly did not cause rust, maintenance became easier. Since the replacement blade of this standard is compatible with the suform, those who have the body (of the flat type of the form) of the form can be used if only purchasing replacement blades.
