OK, I think I know what the problem MIGHT be. First, your hone is fine. I was worried it might be one of those little safety razor hones. Now, if you've been shaving for 3 years with only maintaining your razor with a strop, then it is likely that the bevel is rounded to a degree that the barber hone, which is a touch up stone for maintaining the edge and bevel, is not actually even reaching the very edge of the blade. If you had been maintaining the razor all along with the hone, you would have been fine, but I suspect that your razor now needs its bevel re-set
