Dovo Shavette Black Long Blade Holder: The black razor blade holder is especially for use with the long Dovo Shavette disposable blades. The platinum coated stainless steel Shavette blades can be easily snapped in half to give you two disposable blades. To replace the blade, slide out the black blade holder and insert half the blade into the holder, making sure it is held in place by the notches. Then, simply, close the holder and slide back into the Shavette (you should be able to see the very edge of the blade exposed from the razor). Ensure that the blade is aligned properly before shaving. Dovo Shavettes are a versatile and affordable straight razor that is ideal for travelling and as an introductory razor for newcomers to straight razor shaving.
