Very much agree with the use of cabinet scrapers and/or single edged razor blades for the modern plastic finishes as nothing else will cut through those finishes very well.
However, if it is not a plastic finish and especially if even scraping may take off too much wood, I gave up using most commercial strippers years ago. A lot of traditional finishes will come right off when rubbed with a rolled up pad of paper towels dipped in acetone and rubbed hard on the wood. If the finish is really piled on and or the stock is really dirt/oil stained, I take a bronze "chore girl" kitchen scrubbing pad dipped in acetone and scrub the stock with that. The Chore girl pads don't leave "hairs" that will come back to haunt you later on like steel wool or even some bronze wool will leave.
Acetone also will leave the wood surface less disturbed than many chemical strippers, though you may wish to use very light scraping, fine sanding or boning to smooth the surface down.
What I like about using acetone is that it is completely chemical neutral and you don't have to worry about leaving even trace amounts of chemical stripper in the wood pores. You should wear kitchen rubber dishwashing gloves or something like that when using acetone though as the acetone will dry out the skin of your hands.
Since the early 70's, I've used Easy Off, Dad's and about every commercial stripper made (including Certi Strip and many of the orange based cleaners). I stopped using them about 8 years ago and have never looked back after finally figuring out to use acetone.
