I have ruined numerous items with a fabric shaver. Always due to user error, haha... This fabric shaver has been a game changer for my heavy hand usage.
It is easy to use as it is lightweight and a perfect handheld size. It also includes a protective shield to place over it for items that are not tight knit/woven. The blades are nice and sharp, allowing the tool to glide over the fabric. I have yet to ruin a single item!
I definitely recommend this product.
