Power Seamer vs. Hand Seamer

Power seamers can double lock as fast as 30 feet per minute (fpm) and single lock as fast as 45 fpm. Why, then, would it be necessary to use a hand seamer? There are several conditions where hand seaming is appropriate or preferred. The most common application for hand seaming is preparing a seam for a power seamer. Power seamers must have at least 8 inches of the seam prepared to at least the first stage. (For more on this see Preparing a seam for use with the K9 Power Seamer).

Second are short runs where using a power seamer is impractical.

The final reason to use a hand seamer is when power seaming is impossible. Power seamers are made to work on a very specific, narrow set of tolerances. In real-world applications where seaming situations are less than ideal, or working with hard to form materials, a hand seamer is often the only option. This more traditional seaming method produces a distinctive, hand-crafted look and character that is impossible to get from a power seamer.
