I’ve been using the Izumi KT-11 electric sweater shaver for almost two years and have found it to be by far the easiest and most effective way to remove lint from my sweaters and fleeces. This is not a cheap tool, it costs $50 at Amazon, but it removes more lint than any brush I have tried and does so quickly and with little effort.
The shaver works like an electric hair shaver with a set of blades rotating behind a perforated metal foil. The cutting height is adjustable, with three settings, and the unit can be disassembled for easy cleaning. There are replacement parts available but those too are not cheap. The unit runs on two AA batteries (not included).
While I haven’t tried the previously reviewed Sweater Stone, it sounded like too much trouble and too similar to lint brushes I’ve tried in the past that haven’t worked well for me because they haven’t done a good job of removing heavy lint build-ups effectively, which is what I often have on my fleeces.
I’m embarrassed to admit that I find the KT-11 fun to use. So much so that I have started working my way through my wife’s fleece collection as well.
