Before you spend big money on a new stock, try a cabinet scraper. Cheapest, most valuable tool you'll ever buy or make.
It will shave the top hardcoaot off, leaving the layer of original color and finish in the wood below. Sandpaper will tear the fibers, so stay away from that. Chemical strippers will remove everything, make a mess, and muddy up whatever original color is under there. I've tried it all as I learned, and trust me a cabinet scraper is the fastest method, and also the safest, simplest, and easiest way to not screw it up. After scraping, rub down with some clean mineral spirits. Let it dry and then apply some linseed oilicon or whatever you like.
