I like to score my boules and have used a single edged razor blade in the past. They kept disappearing as my DH uses them for various things around the farm. I decided to buy a REAL lame' for my scoring and found that there is a huge difference. I love my new lame"! It makes much deeper cuts than the razor blade did and it is nice to have something with a handle. It came with a package of blades which will most likely last quite awhile. FYI, I bought it through Breadtopia.
