Nowadays many manufacturers sell clothes shavers. These are a necessary evil for knitters and knitwear lovers. They do a great job of refreshing your knitwear, particularly elbows, cuffs, collars and other high wear, high friction areas. My two favorite sweaters both need an occasional shave to rejuvenate them: one an acrylic shawl collar jacket in an unusual green blend, and the other a long cashmere/angora turtleneck sweater. I've also had a couple of pairs of socks that benefitted from a shave now and then.
If you knit a lot or enjoy knitwear, then a clothes shaver is a must have tool. Although mine has performed well for a number of years, there are some design shortcomings. Read more ... to find out what features I like and which ones fall short.
Summary Some knitwear and yarns will pill, and others will act like lint magnets. Pilling occurs on both inexpensive and expensive yarns and garments, natural and synthetic, though not all. A few yarns and garments will behave impeccably throughout their lives, like good children, but for the others a clothes shaver is an indispensible tool. When this unit ceases to function, I hope there will be a model available that has a longer, more robust cord and switch that can sustain more duty cycles.
