I have never tried the long blades but the dovo shavette has sleeves for at least three different blades: http://www.shaving.ie/products/dovo-shavette-red-green-black-blade-insert-3-pack.html
The dovo shavette blade holders may seem a bit flimsy up close but once you have fed the blade holder into the slot in the razor, the blade is kept nice and firm in place.
