Silky's folding Kataba joinery saw is simply fantastic. It features a no-set Japanese tooth pattern at 22 tpi with elegantly tapered ground blades - once the height of the sawmaker's art. This means you get an amazingly thin kerf (.025") with little, if any, binding or wandering off the layout line. It's perfect for intricate joinery. The Woodboy has two thumb release open positions; one for standard work, the other for tight spots or for kerfing dados. The blade folds into a sure-grip rubberized handle, making it easily portable while protecting the teeth. The unfolded length is 22". Blade length is 9-1/2".
