I have a set. I am very pleased with them. They have sharpened and taken an excellent edge. I did cut myself by just accidentally brushing my finger past the edge... ever so lightly. I have since been paring end grain with impunity.
The results from these chisels showed me the importance of a nicely polished back in the region of the cutting edge. This has prompted me to try to undo some of the damage caused to my red/yellow handled Marples chisels which I allowed to be damp for a number of years while I pursued other interests.
Overall, for £2 each, these Aldi Chisels are excellent. It's a price that makes it more feasible for (re)beginners like me to get some and feel free to practice sharpening without fear that we are about to inflict irreparable damage on some eye-wateringly expensive item.
