Bevel on SRP LE razor (TI)
Okay, I've been having lots of fun playing w/ my diamond film (razors sharper than ever), but I still can't get anywhere w/ this TI. I must have done close to 200 strokes on the D8E (scratch pattern looks good under the scope & passes the magic marker test easily), but when I go to polish it after, it fails HHT miserably and gives a rather half-arsed shave. Not close & uncomfortable. My others are actually smoother than when I used CrO paste!
Most of my razors are done in about 5-6 strokes on each grade of film (maybe more like 10-12 for the higher grits) & I've been doing no less than 20 strokes each on this thing. More than my Friodur by far. Film is still cutting great (lots of swarf), but now I'm starting to worry about wearing out this stuff playing with this one razor.
My only thought is I still have a double bevel. Except the positive sharpie test... Anyone had this problem?

Thanked: 2209They have some tough steel in those razors so it will take more than normal honing to get it where you want it.

Well, I have two of those babies and for touchups I use either the Coticule or my Vintage Escher. It takes a few more strokes to get the job done than most vintage razors but not really a huge number more.

Thanked: 346Yes. The sharpie test, like nearly all other tests, isn't infallible. It merely test for secondary bevels and warped blades. What it fails to detect is the case where there is only one bevel, and it goes all the way to the edge, but the edge is simply too thick - i.e. instead of being 0.3 microns across the edge, it's much larger, like maybe 1 micron or maybe even tens of microns. You could detect this situation if you could examine the edge end-on, but that's awfully tough to do without some specialty fixtures and significant risk to the lenses.
