Before I start on the legs I’ll try it on a piece of scrap first. I have two “2 cherries” mortise chisels but they are about 1/4″ and 3/8″ so those are two small for this work. They have such large handles that I can use them as a sword. Then I have a set of Bahco chisels but they have a sort of curved paring handle. I also have three very cheap hardware store chisels. One of them is 12mm (almost 1/2″). I will compare this with the Lie Nielsen. Thanks to Paul I regain faith in those cheaper ones.
