Louet Double Row Mini-Combs for Spinning Fiber Preparation These handy tools are a unique device which can be used for de-hairing and fine fiber combing. After combing, the fiber can be pulled into a sliver or spun straight from the comb. These combs are made of ash with a lacquer finish and measure 6.5 centimeters (2 1/2") wide. These mini combs are easy on your wrists as they are light weight at 2.4 ounces or 70 grams each. As a safety precaution, all Louet combs are machined so they are not razor sharp.
