Query: Stikit is great!

The Stikit soft hand block is great! Very comfortable in the hand even for long periods of sanding. It allows the paper to conform to gently curving surfaces. Stikit paper may be expensive, but you don't have any waste when using Stikit sanding blocks. I used the Stikit system in building a wood boat, spending many, many hours sanding by hand. I can't imagine a better system for hand sanding!
