It's been a while since I owned a TI razor and believe they do come with a factory shave ready edge. I found it really wasn't all that good of an edge. As far as re setting the bevel if my memory serves me right, I found it to be a bit harder than most new razors. The steel was real hard so I'm not so sure if that 4K is up to the task. As far as getting a "cheap" bevel setter, why? The bevel setter is, imo, THE most important stone you will ever buy.
