I've good mortise chisels, but my bench chisels are largely cheapos. I have them in all widths from 1/8" to 2", with the only quality being the antiques, one a Sorby 1-1/4" and the other a Witherby 3/4". A newer Marples 5/8" is OK but not great.
My 1/8-incher is a hardware store chisel I ground down from its 1/4-inch width, so I took a step yesterday toward quality and bought a Stanley Sweetheart through Amazon, for $20 and change, on sale, free shipping.
For doing dovetails, I would like to get one more in 1/4 or 3/8 width, and will keep shopping, hoping for a deal. Not sure why Amazon had lowered the price on the 1/8-inch Stanley, but they did, and maybe I'll get a deal like that on the next one I would like.
