I picked up a set of the Aldi work zone chisels last week and worked them up quickly. Most of the backs had a slight hallow so that was nice.....I used 150 grit sand paper for flattening the backs...from there I used a standard process of a soft oil stone, hard black, and MDF strop with green compound. It says chrome vanadium steel and it was easy to get a wire edge on the stones.....the edge was as good as anything I have on my narex chisles and the shape and feel is very similar as well.....for 7.00 they are an unbelievably cheap set that seems like they would work great....I am going to give this one away as a gift but I have one more that I might keep as an experiment...anyone else get a set this last week in the USA?
