Very sharp and useful. I originally bought these bits for a set of Incra loops and made several loops out of them. Now I've found all sorts of cool/new uses for these bits. I think it's excellent value for money.
These bits are made from very thick carbide with extra heavy steel. They carefully carved both cherry and oak. It is important that the wood is the correct thickness for the nozzle being used. I'm glad I spent the $$$. The hinges work well.
In terms of precision workmanship, material quality and edge durability I have not used a single bit from any country that even comes close to competing Whiteside bits. Have a question? Imagine calling Whiteside, an American owned and operated manufacturing facility, to get an answer from a design engineer with manufacturing experience.
