The product consists simply of a flat strip of metal 5mm wide and 120mm long, pointed at one end. There is no handle, but it doesn't really need one. It requires an old-fashioned safety razor to be threaded onto it. It therefore holds the razor blade in a curved posture. It's a good idea to use razor blades as you're guaranteed a very sharp cut. Of course, razor blades are a lot sharper than kitchen knives, so it makes a pretty good job of slashing the dough, though a bit of practice is needed to get the knack.
I found, as other reviewers have noted, that sometimes the blade comes off while I'm slashing the dough, as there is nothing other than the tension produced by the blade's curve to hold it on. For such a simple, single strip of metal, a price of £4.25 is rather high. Still, it does the job reasonably well so I'll persevere with it to see if there's a knack to preventing the blade from falling off.
