In fact, you will at times, also see the KFB referred to as a bar increase. It is a fairly common increase, used in knitting patterns.

Actually, increase your stitch count by 1 stitch with one of the simplest ways.

Having said that, knitting into the front and back of the same stitch, creates a bar on the knit side of your fabric. Therefore, the KFB is a visible increase.

Furthermore, this particular increase is a left-leaning increase. In addition, use the increase that works equally well in both stockinette and garter stitch, if used correctly.

As a matter of fact, use in garter stitch, where it is virtually invisible. This is due to the fact that you have bumps on every row in garter stitch. And these garter bumps almost hide the bar.

The knitting abbreviation KFB has many uses. For instance, see it in patterns when you are required to shape a project. An example is when you knit the sleeves of a sweater.

Additionally, when used for shaping, the KFB is often used in conjunction with the PFB. The PFB is the right-leaning equivalent of the KFB.

Moreover, due to the visible bar, the KFB can also be used as a design when used in stockinette stitch in your knitting projects.
