I am considering purchasing some mortise chisels. My two companies to choose from are Blue Spruce Toolworks, and Lie-Nielsen. I can see from the product page on Blue Spruce that their chisels have a full metal tang, and are currently on sale, with the sale to end March 18. Do the Lie-Nielsen also have a full tang? Their product page doesn't show one way or the other, and the description also doesn't say. Disregarding price, which brand would you choose?
