A chin strap is a type of beard, so shaving only part of the beard can create one. Growing the whole beard out first might make the style easier to craft. Precision tools can help make the chip strip thin.
The term "chin strap" can refer to a wide range of similar beards, but all of them are thin. To ensure that it turns out looking great, it might be best to make it progressively thinner through multiple shaves. Small imperfections are especially noticeable on thin beard types, so the grooming tools need to be precise.
After the chin strip has been fashioned, maintaining it is fairly straightforward. However, precise shaving is needed to keep it intact. Small mistakes can ruin the effect, so small shaving tools are needed. Electric razors might lack the precision needed to avoid ruining it.
Few chin strap beards are bushy, and they need to be trimmed on occasion. Those who want a close look may want to consider purchasing a hair trimmer similar to those barbers use. These devices make it easy to pick the perfect height. Those who do not want a close chin strap may prefer to use scissors to get the height they want.
