I have been using a set of the Workzone chisels from Aldi since June of this year. I have had the exact same results as Mike from TN.
I wholeheartedly endorse these chisels. In fact I have used them to build the workbench that Paul Sellers demonstrates and it turned out great.
I am also looking at purchasing a set of the the Narex Chisels. I am just waiting to get them worked into the budget.
