I have used this particular lame (pronounced: ‘lahm’) for over two years and love it. As a home baker, I have tried using different knives and razor blades to slash my loaves, but nothing had all of the features which I was searching for.
It uses a standard, replaceable double-edged safety razor (the type which you can buy at any drugstore) and has a protective cover. It is made of food-grade plastic in France, and has a metal rib that can be bent into any curve which you might like (for creating little “scalloped” effects, etc.). This is the absolute best means of scoring bread.
