I've tried any number of brands of chisels over the years and have always come back to my black handled Stanley's.
They are not made any longer but you may be fortunate enough to find some on the resale market.
I've accumulated twenty or so of these and this has allowed me to turn some into paring chisels, while keeping the bulk of them as they came.
They were sold to schools and cabinet shops until some years back, when they were discontinued.
The steel is excellent, having a Rockwell hardness of C59-61, and they take and hold an edge very well.
I've a Sorby slick that has given good service in heavy work, and a couple of thirty year old Taylor cranked paring chisels that are very nice - but the day to day work is done by the Satanlys.
