I now have 5 TIs, the last from AOS in Las Vegas just last month. The AOS people are as dumb as rocks. They sell a pretty product with a price tag. They knew nothing about straight razors, hones, bevel formation; didn’t even know the knot diameter of their best brush. If their website didn’t say it, they didn’t know it.

I digress. Glenn is exactly right. I used my Shapton Glass series to hone the AOS TI, up to 8k and finished on a Coticule. It is now a fine shaver, as are all my other TIs.
