Today I sharpened my Lowes special Irwin Marples chisels for the first time. I just got these a couple weeks ago and used them on the speaker stands/tables that I made. I noticed that I had chips on the edge of the 1/4 chisel. I sharpened them and was able to get a good solid edge on it again. That leads me to the next question...should I just make do with this set for now, or should I start to hunt around for a set of used high quality chisels? I saw a review of the Narex Richters, but outside of that...I really don't know squat about them. Help!!
