This guide is intended to cover the basics (and specifics) of kitchen knife selection, care, and terminology. The goal is to provide a guide to purchasing the perfect knives for your budget and uses.
Before getting on to a discussion of the knives themselves, it is important to understand the terms that will be used to discuss them.
- The bevel is the actual angle of the sharpened edge of the knife (not the angle of the flats of the blade!). Bevels on western-style knives (German and French) tend to stay around 20°. Bevels on Japanese knives tend to be shallower, usually around 15°. Most knives available today are double-bevel, meaning that they are ground and sharpened on both sides of the blade, but some traditional-style Japanese knives are single-bevel (ground and sharpened on only one side of the blade). The bevel angle is the single most important piece of information when having your knives sharpened or sharpening them yourselves.
- The point, the blade, and the handle - If you don't know what these are, you probably shouldn't be in a kitchen.
- Forging - Most high-quality western style knives are forged. That is, the material is brought to high temperatures and then hammered into shape. For most modern mass-produced forged knives, this is done by using machines to hammer the metal into die forms, a process known as drop forging. Hand-forged knives are pretty much relegated to blacksmiths turning out custom knives or small runs of popular designs.
- Stamping - Also known as blocking, stamping is the process of cutting the knife profile directly from rolled steel, which is then ground and sharpened. Most inexpensive western style knives are stamped. Oddly, most high-quality mass-produced Japanese knives are also stamped, and have the bolster welded on. Stamped knives tend to be thinner and lighter than forged knives, but with high-quality steels can equal their forged brethren in edge-holding capability.
- Stainless Steel - The most popular material for knives by far, stainless steels are alloyed from iron and various other metals (usually chromium, nickel, carbon, and molybdenum) so that the resultant material does not tarnish or rust. Stainless steels are generally softer than carbon steels in the same price range, and the best carbon steels will always be harder (and thus hold an edge longer) than stainless steels.
- Carbon Steel - Carbon steels are generally alloyed from iron and carbon, with little else coming into play. Knives made of carbon steel can reach very high levels of hardness, but tarnish and rust easily, and thus must be oiled regularly and washed and dried quickly after use.
- Ceramic - A relative newcomer to the knife scene, hard ceramics have the advantage of extremely long edge-holding capability, at the cost of brittleness, expensive maintenance (when needed), and smaller available sizes. Expect further advances in the field of ceramic materials to expand their prevalence in cutlery.
Choosing Your Knives
The Very Basics
- Chef's Knife - More than 90% of what you're going to be doing in the kitchen can be accomplished with a chef's knife. If you're going to spend money on a knife, spend it on this one. Ideally, you should try some out in a store to see whether you like a full bolster or not. Comparing Wusthof or Henckels to Shun or Global at a Williams-Sonoma is a good idea; they'll let you handle the knives. This will also give you an idea if you like the heaver forged German blades or the lighter stamped Japanese style. Modern Japanese Gyutos are very similar to western chef's knives, with the main difference being a shallower belly. The following knives are recommended.
- Under $30
- Under $60
- Around $100
- More than that
- Way more than that
- I don't know what you're buying here, but I'd be scared to use it to cut anything harder than a marshmallow.
