Update on previous thread:
Garrett Wade contacted me after the previous posting and offered a set of chisels for my use to test their new line. They said that they had been shipped to them with the wrong color scheme. This is their new line with steel all the way through the handles.
I sharpened the set using the scary sharp method, taking about 5 hours to complete. Thought that the backs flattened rather quickly. They took a good edge.
IMHO the ones I was given are way too soft for use in hardwoods and maybe even softwoods. I used the 3/8" one to work on some 22 year old spruce and was surprised at how quickly it dulled. Today I tested the other 5 in red oak. Each one dulled after 5 -8 impacts at 90 degrees and cross grain. My tests are not done in a scientific manor though.
I have reported this back to Garrett Wade.
