Victorinox, by a long shot.
I can still take a Vic blade to the next level though so even they don't go right into use out of the box. With good steel, my sharpmaker, and my stropping system using HA diamond slurry, I can get hair whittling performance and am never satisfied until that is achieved.
Schrade Walden 1095 from yesteryear is my steel of choice. I have a 225h, a single spring 787, some 863 whittlers, a few 881s, and a couple of 804 big whittlers that either had the factory edges or worn edges when I got them. You can pick one of them out of my safe and whittle hairs with them. My technique is decent....but that good, old 1095 makes the difference.
Love that steel.
